METHOD OF MANUFACTURING CATALYST FOR DIMETHYL ETHER AND METHOD OF MANUFACTURING DIMETHYL ETHER

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a catalyst for manufacturing a dimethyl ether at a high yield and a method of manufacturing the dimethyl ether at a high space time yield. SOLUTION: This method of manufacturing the catalyst for manufacturing the dimethyl ether comprises suspending a methanol synthesis catalyst, methanol dehydration catalyst and aqueous gas shift catalyst in a solvent in such a manner that all of the differences in the values of A expressed by the following equation between the respective catalysts attain the values within ±1×10<-6> g/cm: A=D<2> .(P-S) where, D is the average grain size of the catalyst and its unit is cm; P is the density of the catalyst and its unit is g/cm<3> and S is the density of the solvent and its unit is g/cm<3> . This method of manufacturing the dimethyl ether comprises circulating a gaseous mixture composed of carbon monoxide and hydrogen or a gaseous mixture included with carbon dioxide and/or steam further therein through the catalyst obtained by the method of manufacturing the same described above.
