Improvement in alkene selectivity in the conversion of dimethyl ether into hydrocarbons by control of absorption by heteropoly compounds

Abstract

In the conversion of dimethyl ether into hydrocarbons over dodecatungstophosphates, the alkene : alkane ratios in the products depend on the ability of these tungstophosphates to absorb dimethyl ether; the alkene selectivity is greatly increased as the contribution of the bulk phase of the Catalysts (‘pseudo liquid phase’)decreases.
