Abstract
The present invention provides an improved process for the preparation of phosphorous containing mesoporous alumina catalyst for selective dehydration of methanol to dimethyl ether. The process provides a single step selective vapor phase dehydration of methanol to produce dimethyl ether over phosphorous containing mesoporous alumina (P/Al2O3) catalyst at a temperature in the range of 150-350° C. The process provides methanol conversion of 45-100% with a selectivity of the DME up to 100%.
