膜反応器における凝縮性生成物の高純度化方法

Japanese Patent JP7435553

B2

An object of the present invention is to provide a method for highly purifying a condensable product in a membrane reactor, which can highly purify the condensable product by improving the substance amount ratio of one condensable product in the largest amount among two or more condensable products that have permeated to the permeation side of the membrane reactor. The method for highly purifying a condensable product in a membrane reactor in the present invention includes: a synthesis reaction step of introducing a raw material gas containing at least one of carbon monoxide gas and carbon dioxide gas, and hydrogen gas into a first space of a membrane reactor including a separation membrane, the first space being on a non-permeation side and filled with a synthesis catalyst, and a second space being on a permeation side, to synthesize two or more condensable products; a membrane separation step of causing the condensable products generated in the first space in the synthesis reaction step to permeate into the second space through the separation membrane for separating; and a decomposition reaction step of decomposing the condensable products that have permeated into the second space, and improving the substance amount ratio of one condensable product in the largest amount among the condensable products that have permeated.
