CONVERSION OF SYNGAS TO DIMETHYL ETHER

摘要

CONVERSION OF SYNGAS INTO DIMETHYL ETHER Synthesis gas, optionally together with water, is contacted at 232 to 399.degree.C with a catalyst comprising coprecipitated Cr, Cu and Zn components in which the atomic ratio Cr/(Cu+Zn) is 0.1 to 1.0 and an acidic dehydrating component and aged catalyst is regenerated by contact with an oxygen-containing gas at 38 to 538.degree.C.
