ABSTRACT:
A method for producing dimethyl ether by forming a slurry by introducing a catalyst into a solvent and introducing a mixed gas comprising carbon monoxide and hydrogen into the slurry. The catalyst 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 the alumina particles.
