CATALYST FOR REFORMING DIMETHYL ETHER, METHOD FOR MANUFACTURING THE CATALYST AND METHOD FOR PRODUCING HYDROGEN-CONTAINING GAS

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for reforming dimethyl ether having high activity and durability even in a comparatively high temperature range in a reforming reaction of dimethyl ether and to provide a method for manufacturing the catalyst for reforming dimethyl ether and a method for producing a hydrogen-containing gas, by which the hydrogen-containing gas can be produced even in the comparatively high temperature range.

SOLUTION: The catalyst for reforming dimethyl ether is obtained by blending metal oxide particles, each of which contains copper and zinc as principal metal components and which are prepared by screening to have ≤0.5 mm particle size, with activated alumina particles which are prepared by screening to have 0.5-2 mm particle size. The method for manufacturing the catalyst for reforming dimethyl ether comprises the steps of: preparing the metal oxide particles, each of which contains copper and zinc as principal metal components and which have ≤0.5 mm particle size, by screening; preparing the activated alumina particles having 0.5-2 mm particle size by screening; and blending the prepared metal oxide particles with the prepared activated alumina particles. The method for producing the hydrogen-containing gas comprises a step of reacting dimethyl ether with steam in the presence of the catalyst for reforming dimethyl ether.
