Abstract
A feedstock comprising a hydrocarbon containing 2 or more carbon atoms in the molecule and/or a hydrocarbon derivative containing hydrogen-carbon links is converted to olefins over the zeolite NU-3. When in particular the feedstock is methanol or dimethyl ether olefins are formed with high selectivity against formation of aromatics.
Claims6
A process for making an olefin containing 6 or fewer carbon atoms in the molecule by reacting over a catalyst a feedstock comprising an oxygenated hydrocarbon and recovering the olefin from the products of the reaction, the said catalyst comprising zeolite NU-3 as defined in Table 1 hereinbefore.
