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

摘要

A catalyst suitable for producing dimethyl ether comprises alumina particles having an average size of 200 mu m or less and a methanol synthesis catalyst layer formed around each of the alumina particles. The methanol synthesis catalyst has a weight ratio of 0.05 to 5 to a weight of the alumina particles. The catalyst is produced by forming a layer comprising a methanol synthesis catalyst around each of alumina particles. The dimethyl ether is produced by the method of foming a slurry by introducing the catalyst into a solvent and introducing a mixed gas comprising carbon monoxide and hydrogen into the slurry.
