報告摘要：
Our comfortable modern life is supported by numerous chemical, in particular petrochemical, products. Because of the shale gas revolution, the use of methane as chemical feedstock as well as fuels is attracting great attention. Now methanol is getting more available chemical feedstock and methanol to olefins (MTO) reaction is a promising route to lower olefins as basic raw material. For the MTO reaction, currently, industrial processes use ZSM-5 (MFI) and SAPO-34 (CHA) zeolites. We have found CIT-1 (CON) zeolite is promising for selectively converting methanol to propylene and butenes without serious loss of activity. Bioethanol has been widely used as additive and alternative to gasoline. Ethanol can be easily converted to ethene and in Brazil etc. BiproPE and PET30 (30% from biomass and 70% from petroleum) are commercialized. Even PET100 can be manufactured by synthesizing p-xylene via various routes using zeolite catalysts starting from biomass resources. We have found an effective transformation of glucose to HMF over Beta (*BEA) zeolite by finely tuning acid properties. Meanwhile, a great deal of effort has been devoted to the production of sorbitol, as bio-based feedstock, from cellulose. We have developed highly active zeolite catalysts for the dehydration of sorbitol to isosorbide in water. For a future sustainable chemicals scenario, it may be desirable to develop efficient methods for utilizing CO2 by using renewable energy, which could be the ultimate goal. Photocatalytic decomposition of water by visible light, which accounts for a great majority of sunlight, is an enormous challenge and it is absolutely necessary to activate the research in this field. In Japan a 10-year national project named ARPChem (Artficial Photosynthesis of Chemicals) that targets recycling CO2 by using solar H2 started in 2012. At this moment this project focuses on the production of light olefins as chemical feedstock. We are developing the process consisting of methanol synthesis from CO2 and H2, followed by the MTO reaction catalyzed by zeolites.
