ABSTRACT:
This invention discloses a process for converting heterosubstituted methanes, such as methyl alcohol, methyl ether, methyl mercaptan, dimethyl sulfide, methyl halides, methylal, methylamine and the like, by contacting such methanes with bifunctional acid-base catalysts at elevated temperatures, between 200.degree. and 450.degree. C., preferably between 250.degree. and 375.degree. C., to produce predominantly lower olefins, preferably ethylene and propylene. The catalysts of preference are those derived from halides, oxyhalides, oxides, sulfides or oxysulfides of transition metals of Groups IV, V, VI, VIII of the Periodic Table, such as tantalum, niobium, zirconium, tungsten, titanium, chromium and the like, deposited on acidic oxides and sulfides such as alumina, silica, zirconia or silica-alumina.
