Catalyst for dimethyl ether, method of producing catalyst and method of producing dimethyl ether.

摘要

PROBLEM TO BE SOLVED: To provide the subject synthesizer reduced in cost through diameter reduction of a slurry bed-type reactor for dimethyl ether synthesis to be used at high pressures. SOLUTION: This dimethyl ether synthesizer divided into upper and lower two vessels 11, 12 is so designed that a feedstock gas charge pipe is connected to the upper space of the lower vessel 12 or the slurry bed section of the upper vessel 11, a reaction product gas discharge pipe 13 is connected to the upper space of the upper vessel, and a piping for circulating unreacted gas separated from the reaction product gas is connected to the slurry bed section of the lower vessel.
