PROCESS FOR PREPARING C2-C4 OLEFINS FROM METHANOL/DIMETHYL ETHER

摘要

C2-C4-olefins are prepared by catalytic conversion of methanol and/or dimethyl ether in the presence of a zeolite catalyst at elevated temperatures by a process wherein the catalyst used is a borosilicate zeolite which is treated with hydrogen fluoride, molded together with an amorphous aluminosilicate as a binder and then treated with hydrochloric acid.
