METHANOL-PRODUCING DEVICE AND METHANOL-PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a methanol-producing device which is used for producing methanol from a gas containing carbon dioxide and hydrogen as a raw material gas, can sufficiently enhance a methanol conversion rate over an equilibrium conversion rate at the prescribed temperature and pressure, does not need a methanol distillation process for the separation of the methanol and the water which are reaction products, and can lower production cost.

SOLUTION: This methanol-producing device for reacting a raw material gas containing hydrogen and carbon dioxide in a reactor 1 in the presence of a catalyst and an organic solvent to produce the methanol is characterized in that the reactor 1 is formed to react the raw material gas in such reaction conditions that the methanol as one of the reaction products becomes a gas and by-produced water as the other becomes a liquid, and a selectively water-penetrating membrane 10 for selectively separating off the water from a liquid phase containing the by-produced water outside the liquid phase is disposed in the reactor.
