Obtaining of Environmental Motor Fuel with Low Durene Content of Dimethyl Ether

Abstract

There was showed selective modifying additive effect of cerium, magnesium and zinc oxides on the activity and selectivity of zeolite catalyst from pentoxyl group in oxygenates conversion reaction (methanol and dimethyl ether) into liquid hydrocarbons. There was stated that the conversion of oxygenates in the stream of synthesis gas promotes the stable operation of zeolite catalyst, thereby forming a high-octane component of motor gasoline with low durene content (not more than 5% by mass). Obtained results demonstrate the expediency of preparation of hydrocarbons from synthesis gas without isolation step followed by conversion of oxygenates in synthetic gasoline.
