Japan - Germany Joint Research on Cl Chemistry

This particular research program was primarily intended to develop Cl chemistry, namely research and development of catalysis and the related technology for producing basic chemicals and liquid fuels from carbon monoxide, methane and methanol. Initially the research project was executed in cooperation with German Democratic Republic, but finally with new Federal Republic of Germany because of the unification of GDR and FRG in October 1990.Following four main subfects were selected to be intensively pursued based on the discussions during the first meeting in 1988. Namely, (1) Heterogeneous catalysis for carbonylation of methanol to produce acetic acid, (2) Selective hydrogenation of carbon monoxide to oxygenates such as alcohol, aldehyde etc.. (3) Synthesis of novel zeolite and its physicochemical evaluation, and (4) Advanced chemical utilization of methane.The research was promoted in various ways of cooperation, that is mutual exchanges of fresh private informations, proprietary samp … More les to be evaluated and visiting researchers. Workshops for presentation of the papers and discussions were also held. The outcome of the results has been published in the international journals and especially in an special issues of proceedings and distributed among the worldwide chemists of the related specialties. Selected topics are outlined as follows.An unique catalyst had been developed in The University of Tokyo for synthesizing acetic acid by carbonylation of methanol. The catalyst comprises Ni loaded on active carbon. Aging mechanism of the catalyst was investigated in cooperation with German Central Institute of Organic Chemistry. Further development of catalyst is now pending due to the reorganization of German chemical industry after unification. Reaction mechanisms and the roles of the catalyst were investigated, by joint work between Hokkaiao University and German Central Institute, leading to the selective conversion of synthesis gas selectively to useful oxygen containing compounds such as ethanol, propanol, acetaldehyde etc.. Synthesis and modification of novel zeolitic materials have been successfully studied for selective conversion of methanol to olefins and/or aromatics, wherein particular attentions being paid on the evaluations of in pore diffusion of molecules and acidic properties. Promising catalysts for oxidative coupling of methane was developed to produce ethane and ethylene. Less
