摘要： Olefins are prepared by converting 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 has been molded together with an amorphous binder containing aluminum oxide and silicon dioxide. The advantage of using the borosilicate catalyst is that the yield of C.sub.2 -C.sub.4 -olefins is improved at the expense of formation of higher hydrocarbons.
