C1化学における分離膜技術展開の可能性

抄録

C1 chemistry, production technologies of fuel and chemicals from syngas, includes processes that would be possible to improve their productivity, to save energy requirement, and thereby to reduce production costs by selectively removing products from syngas through membrane. In this report, the results of process simulation on methanol synthesis are introduced to discuss about efficiency of membrane reactor in this process. The process simulation demonstrated that methanol productivity was substantially improved by removing products, methanol and water, in situ from the reaction system. A key issue is to develop microporous inorganic membranes enabling us to separate products like water and alcohol at high temperatures up to 300℃ and high pressures up to 100 atm.
