PapersFractal dimensions of activated carbons prepared from lignin by chemical activationIn refereedAcademic JournalCo-authorHayashi Jun'ichi;Muroyama Katsuhiko;Gomes V.G.;Watkinson A.P.CarbonVol.40, No.4 630-6322002~Activated carbons were prepd. from lignin by pyrolysis and use of the activating agents NaOH, KOH, ZnCl2 and H3PO4. It was demonstrated that ZnCl2 and H3PO4 worked effectively as activating reagents at temps. below 873 K, and the change of the sp. surface above 873 K was due to the thermal shrinkage. The activating agents NaOH and KOH worked effectively at temps. above 873 K, and an increase of the sp. surface area was found for temps. of 773-1073 K, due to pore development by activation. At temps. above 1073 K the sp. surface area decreased.
PapersPreparation of molecular sieving carbon from waste resin by chemical vapor depositionIn refereedAcademic JournalCo-authorHorikawa Toshihide;Hayashi Jun'ichi;Muroyama KatsuhikoCarbonVol.40, No.5, 709-7142002~Mol. sieving carbons were prepd. from carbonized phenol-formaldehyde resin wastes by the CVD of the pyrolyzed carbon from the hydrocarbon species. The pore size can be controlled in the range 0.37-0.42 nm by changing the hydrocarbon species pyrolyzed, pyrolyzing temp., and processing time. Some of the carbons have an excellent selectivity for sepg. CO2 and CH4, and others for sepg. C3H8 and C3H6. As the mechanism for controlling the pore size during CVD processing, adsorption of hydrocarbon mols. first takes place on the pore surface and then the adsorbed hydrocarbons pyrolyze to give carbon. Therefore, the pore size of the carbons can be adjusted by controlling the amt. hydrocarbon adsorbed on the phenol-formaldehyde resin char.
PapersActivated carbon from chickpea husk by chemical activation with K2CO3: preparation and characterizationIn refereedAcademic JournalInternational coauthorshipHayashi Jun'ichi;Horikawa Toshihide;Muroyama Katsuhiko;Gomes V.G.Microporous and Mesoporous MaterialsVol.55, No.1, 63-682002~Activated carbon was prepd. from chickpea husk by chem. activation with K2CO3. At 1073 K, the sp. surface area of activated carbon prepd. with an impregnation ratio of 1.0 yielded the max. value of 1778 m2/g. From the results of the yield of the activated carbon and the reagent recovery ratio, it was concluded that the carbon involved in the husk char was removed as CO by redn. of K2CO3 above 1000 K. The fractal dimension changed slightly between 773 and 973 K, and it decreased rapidly between 973 and 1173 K. It was deduced that this decrease of the fractal dimension was due to the decompn. of the cross-linked structure and the small crystallite structure. The micropore vol. and the sp. surface area increased by the release of plugged pore due to the decompn. of the cross-linked structure. It was further deduced that the mesopore vol. increased and the micropore vol. decreased by combination of micropores due to the decompn. of small crystallites.
PapersPreparing activated carbon from various nutshells by chemical activation with K2CO3In refereedAcademic JournalInternational coauthorshipHayashi Jun'ichi;Horikawa Toshihide;Takeda Isao;Muroyama Katsuhiko;Nasir Ani FaridCarbonVol.40, No.13, 2381-23862002~We have prepd. activated carbons by chem. activation with K2CO3 from five kinds of nutshells: almond shell, coconut shell, oil palm shell, pistachio shell, and walnut shell. When prepd. at 1073 K, the activated carbons from all the nutshells had the max. sp. surface areas. Based on the max. values of sp. surface area, the activated carbons prepd. were classified into two groups: Group-L and Group-S. The former group included activated carbons with high sp. surface area and the latter included those with lower sp. surface area, resp. It was found that K2CO3 effectively worked as an activation reagent, but differently in the temp. ranges below 800 and above 900 K. Due to impregnation, cellulose and hemi-cellulose were modified by K2CO3 and accordingly the wt. loss behaviors of the nutshells were changed in the temp. range below 800 K. In the temp. range above 900 K, carbon in the chars was removed as CO by the redn. of K2CO3 to increase the sp. surface area and the pore vol. It was deduced that the difference between the sp. surface areas of Group-L and those of Group-S correspond to the difference between wt. loss behaviors in the temp. range above 900 K.
PapersSynthesizing activated carbons from resins by chemical activation with K2CO3In refereedAcademic JournalInternational coauthorshipHayashi Jun'ichi;Uchibayasi Mikito;Horikawa Toshihide;Muroyama Katsuhiko;Gomes V.G.CarbonVol.40, No.15, 2747-27522002~We prepd. activated carbons from phenol-formaldehyde (PF) and urea-formaldehyde (UF) resins by chem. activation with K2CO3 with impregnation during the synthesis of the resins. The influence of carbonization temp. (773-1173 K) on the pore structure (sp. surface area and pore vol.) and the temp. range at which K2CO3 worked effectively as an activation reagent, were investigated. The sp. surface area and micropore vol. of PF-AC and UF-AC increased with an increase of carbonization temp. in the range of 773-1173 K. We prepd. activated carbon with well-developed micropores from PF, and activated carbon with high sp. surface area (>3000 m2/g) and large meso-pore vol. from UF. We deduced the activation mechanism with thermogravimetry and X-ray diffraction. In prepg. activated carbon from PF, K2CO3 was reduced by carbon in the PF char. The carbon was removed as CO gas resulting in increased sp. surface area and pore vol. above 1000 K. In prepg. AC from UF, above 900 K the carbon in UF char was consumed during the K2CO3 redn. step.

PapersPreparation of mesoporous material having a hydrophobic surface by combining silica xerogel with resin using sol-gel methodIn refereedAcademic JournalCo-authorHayashi Jun'ichi;Watada Yuki;Muroyama KatsuhikoMaterials LettersVol.50, No.2-3, 87-912001~We tried to prep. a mesoporous material with a hydrophobic surface by combining silica xerogel with phenol-formaldehyde resin using the sol-gel method. During the procedure, the formation of the silica xerogel and the formation of phenol-formaldehyde resin simultaneously occurred in the liq. phase. Then, the pore structure of the xerogel was different from the simple mixt. of silica xerogel and phenol-formaldehyde resin. It is found that the pore size can be tailored by changing the phenol-formaldehyde resin ratio.

A carbonaceous starting material, oil palm shell, which can be found easily and abundantly in the country of Malaysia, has been used in the process to obtain various type of adsorbents for gas adsorption and sepn. applications. Pyrolysis, activation and chems. impregnation have been applied for the prodn. of the products. The adsorbents produced were verified for its phys. characteristics using scanning electron microscope (SEM), thermogravimetry (TG) anal. and mol. probe technique. A gas chromatog. unit has been used as gas analyzer and a single column adsorber has been used for the adsorption kinetics expts. on several mixed gas system. In this study, mixed gases like CO2/CH4 was used for the sepn. performance tests. Adsorption uptake curves of the products were recorded and discussed for the adsorption behaviors on mixed gas system. The results have shown a great feasibility of using carbon products from oil palm shell as an adsorbent for gas sepn., which are applicable and useful in chem. processing industries. In addn., the development of this material is useful and economical and can be further introduced as adsorbent for pressure swing adsorption application.

PapersPreparation of activated carbon from lignin by chemical activation.In refereedAcademic JournalInternational coauthorshipHayashi Jun'ichi;Kazehaya Atsuo;Muroyama Katsuhiko;A.P. WatkinsonCarbonVol.38 No.13, 1873-18782000~Activated carbons were prepd. from lignin by chem. activation with ZnCl2, H3PO4 and some alkali metal compds. The influence of carbonization and activating reagent on the pore structure of the activated carbon was investigated. It was found that the max. surface areas were obtained at the carbonization temp. of 600C in both ZnCl2 and H3PO4 activation, and that the surface areas were as large as those of the com. activated carbons. On the other hand, in alkali metal activation it was found that the max. surface areas were obtained at the carbonization temp. of 800C. Except for Na2CO3 max. surface areas were much larger than those of the com. activated carbons. The activated carbon prepd. by K2CO3 activation showed a surface area of nearly 2000 m2/g. It was shown that ZnCl2 works effectively as dehydration reagent below 600C. On the other hand, K2CO3 works effectively in two temp. ranges, below 500C and above 600C. Below 500C, the carbonization behavior was modified by impregnation with K2CO3, but the pore structure changes little. Above 600C, carbon was consumed by K2CO3 redn. and then the surface area was increased.

PapersMechanism of Chemical Activation with K2CO3 in Preparation of Activated Carbon from Beau-curd RefuseIn refereedAcademic JournalCo-authorHayashi Jun'ichi;Muroyama Katsuhiko;Furukawa Akira;Takemoto SusumuKagaku Kogaku RonbunshuVol.25, No.1, 45-501999~We attempt to prep. activated carbons from bean-curd refuse by chem. activation with K2CO3. Activated carbon with high sp. surface area of 2656 m2/g can be prepd. at a carbonization temp. of 800.degree.. During an impregnation, the K2CO3 added reacts with bean-curd refuse and changes to KO2 and K2C2O4. Then, the bean-curd refuse is modified and the water-sol. org. components in the bean-curd refuse increase. At a carbonization temp.<500.degree., the carbonization behavior of bean-curd refuse is changed by the modification, and the sp. surface area of the carbonized bean-curd refuse becomes larger. At temps.>700.degree., K2CO3 is reduced to potassium. The carbon is consumed by redn. of K2CO3.

The surface area of SiO2-I xerogel was larger than that of the monolithic SiO2 xerogel. The pore size distribution shifted to smaller radii, and the peak in the distribution curve became sharper, as the I ratio increased from 0 to 0.01. The added I was bridged between SiO2 xerogel matrix, and then the pore structure of xerogel was changed.

PapersProduction of Activated Carbon with High Specific Surface Area from Bean-curd Refuse by Chemical ActivationIn refereedAcademic JournalCo-authorMuroyama Katsuhiko;Hayashi Jun'ichiTANSONo.172 95-991996~We tried to produce activated carbons with high sp. surface area from bean-curd refuse by chem. activation using several alkali metal compds. such as K2CO3, NaOH and Na2CO3, and H3PO4 as the reagent. The effects of carbonization temp., holding time, and impregnation ratio of reagent to dried bean-curd refuse on pore structure of the activated carbons produced were investigated. Among chems. tested K2CO3 is found to be the most effective as the impregnation reagent. In a range of carbonization temp. above 700.degree.C, the sp. surface area of the activated carbon produced increases rapidly to a max. at about 800.degree. and decreases with further increase in temp.>800.degree.. The sp. surface area attains a max. at a holding time of about 60 min. The sp. surface area increases with increasing impregnation ratio up to an impregnation ratio of 1.00, beyond which it gradually decreases with further increase in the impregnation ratio. The sp. surface area of activated carbon produced under the suitable conditions from the bean-curd refuse impregnated with K2CO3 is as high as 2656 m2/g. It is found that K2CO3 changes the carbonization behavior of the bean-curd refuse in a range of lower temp. below 400.degree.C and reacts further with the carbonized material to increase the sp. surface area in a range of higher temp. above 600.degree.C.

PapersProduction of Activated Carbon from Bean-curd Refuse by Chemical Activation with ZnCl2In refereedAcademic JournalCo-authorHAYASHI,Jun'ichiTansoNo.166 34-391995~In an effective utilization of bean-curd refuse we tried to produce activated carbon from bean-curd refuse by chem. activation with ZnCl2. We examd. the influence of prodn. conditions such as carbonization temp., holding time and impregnation ratio on the pore structure of activated carbon produced. The surface area of the activated carbon produced were calcd. from the N2 adsorption isotherms data by BET method. The max. surface area was obtained for the activated carbon produced at a carbonization temp. of 550.degree.C for holding time of 60 min. The surface area increased with an increase of impregnation ratio in the range of impregnation ratio up to 0.87 and this resulted from the development of micro-porosity. However at an impregnation ratio beyond 0.87, meso-porosity were developed and therefore the surface area increased a little. We succeeded in producing activated carbons with surface area more than 1000 m2/g from bean-crud refuse by chem. activation. We found that ZnCl2 changed the carbonization behavior of bean-curd refuse at 200 to 400.degree.C and that the activated carbon with high surface area was produced.

PapersA Shape-Selective Catalyst Utilizing A Molecular Sieving Carbon with Sharp Pore DistributionIn refereedAcademic JournalCo-authorMiura Kouichi;Hayashi Jun'ichi;Kawaguchi Tatsuo;Hashimoto KenjiCarbonVol.31, No.5 667-6741993~The authors have previously presented a new method for prepg. mol. sieving carbon (MSC) from coal modified by pitch and PhOH-HCHO (PF) resin. By resorting to this method, the authors could prep. MSCs with sharp pore distributions around 0.37-0.45 nm in diam. In this paper the possibility of using the MSC as a catalyst support that shows shape selectivity was examd. MeOH decompn. was performed at 350-450.degree. on the MSC supporting Ni as a model reaction. MeOH is known to be decompd. to CO and H2 first, then CH4, CO2, and H2O are produced through reactions between CO and H2. It was possible to produce only CO and H2 by using MSCs with sharp pore distributions around 0.45 nm in diam. On the other hand, all the products were detected by use of the activated carbon whose pore distribution was broadened through steam activation of the MSC. This difference was found to be derived from the difference in the pore distributions between the MSC and the activated carbon. Thus it was clarified that the MSC with sharp pore distribution can be used as a shape-selective catalyst support.

By changing carbonization temp., coal-PhOH-HCHO resin mixing ratio, and modifying org. compd., the MSCs were prepd. having sharp pore distribution with .apprx. 0.37-0.44 nm pore diam. The possibility of using MSCs for sepn. of gas. mixts. C3H8-propylene, 1-butene-isobutene, and CO2-CH4 were examd. from the viewpoint of adsorption isotherm and adsorption rate. The MSCs prepd. successfully sepd. each of the gas mixts. by the difference in adsorption amts. The MSC with intraparticle diffusivity for CO2 40-fold higher than that for CH4 was also prepd.

The compressive strength of cokes produced by carbonizing the caked coals to 800.degree. was very high, but the CO2 reactivity of the cokes was also very high, in comparison with a com. coke. It was essential to apply pressure on the coal at 300-450.degree. during pyrolysis. Thus, coke could be produced from non-coking coals, but not from coking coals, by this method. This was attributed to the observation that volatile material could not be removed from coking coals under pressure.
PapersProduction of Molecular sieving Carbons Through Co-carbonization of Phenol-formaldehyde resin and Other organic SubstrateIn refereedAcademic JournalCo-authorMiura Kouichi;Hayashi Jun'ichi;Hashimoto Kenjiadsorption;adsorptionCarbonVo.30, No.6, 946-6471992~Mol. sieving carbons were prepd. by co-carbonization of PhOH-HCHO resin with small amts. of anthracene, dihydroanthracene, and acenaphthylene with final carbonization temps. 600 and 900.degree.. There was some interaction between the resin and anthracene while the anthracene-contg. resin was carbonized. The other modifiers also affected the carbonization behavior of the resin. The micropore vols. of all co-carbonized materials accessible to CO2, C2H6, BuH, and Me3CH showed sharp distributions, suggesting that the carbons may be suitable for mol. sieving.
PapersRapid production of metallurgical coke by using a moving bed reactorIn refereedAcademic JournalCo-authorKouichi Miura;Jun'ichi Hayashi;Noriaki Sano;Kenji Hashimoto;Haruhisa IwakiriNippon Enerugi GakkaishiVol.71, No.12 1184-11921992~A moving bed reactor was simulated and nstructed by assuming a new type of coke oven which oduces metallurgical coke rapidly and continuously. Using this reactor, a trial was run to produce metallurgical coke from 4 kinds of coals. The new coke oven had a unique heating pattern of coal; rapid heating up to 450-500, holdup time for 20-30 min, and subsequent slow heating up to 800. This heating pattern of coal was realized by using moving bed reactor; the coke comparable to a com. coke from the viewpoint of the CO2 reactivity and the micro strength was produced in .apprx.2 h from highly coking coals. The coke comparable to the com. coke could also be produced from a slightly coking coal by mixing it with a highly coking coal or by adding a pitch.
PapersProduction of molecular sieving carbon through carbonization of coal modified by organic additivesIn refereedAcademic JournalCo-authorHAYASHI Jun'ichi;Miura Kouichi;Hayashi Jun'ichi;Hashimoto KenjiCarbonVol.29 No.4-5 653-6601991~A method is presented for producing mol. sieving carbon from coal. Finely ground coal particles were mixed with coal-tar pitch, PhOH, and HCHO at 95.degree. to be agglomerated through the formation of PhOH-HCHO resin. Then the agglomerated particles were solely carbonized in an inert atm. to produce chars. The chars thus prepd. have pore structure different from that of the chars prepd. from the original coal. By changing the carbonization temp. and the mixing ratio of coal, pitch, PhOH, and HCHO, several kinds of mol. sieving carbons with sharp pore distribution .apprx.0.35 nm in diam. were prepd. One of the mol. sieving carbons thus produced is expected to be used successfully for the prodn. of N from air by the pressure-swing adsorption process.
