Abstract
Olefins are produced by reacting a feedstock containing a hydrocarbon containing 2 or more carbon atoms in the molecule and/or a hydrocarbon derivative containing hydrogen-carbon links over a catalyst comprising 'FU-1,' which is a zeolite-like silica-containing material characterized inter alia by chemical composition and X-ray diffraction pattern. The feedstock is preferably methanol or dimethyl ether. The predominant olefin product can be controlled according to the reaction conditions used. Conversion to aromatics is very low.
