The invention relates to a process for converting a feed stream consisting of reactive components and an optional feed diluent to a product stream comprising aromatic hydrocarbons and C2-C3 olefins, wherein the reactive components comprise at least 90 vol % of an aliphatic ether selected from the group consisting of methyl tertiary butyl ether and ethyl tertiary butyl ether, the process comprising the step of contacting the feed stream with a catalyst composition comprising a zeolite catalyst, wherein the zeolite catalyst is a zeolite modified by Ga and an element M1 selected from the group consisting of Zn, Cd and Cu.

Process for conversion of lower aliphatic ethers to aromatics and lower olefins

The present invention relates to a process for producing lower olefinic hydrocarbons by oxidative dehydrogenation of paraffinic lower hydrocarbons. More particularly the present invention provides a process for converting a feedstream comprising a paraffinic lower hydrocarbon and carbon dioxide to a product stream comprising an olefinic lower hydrocarbon and synthesis gas in the presence of the catalyst composition La&#x2014;Mn/inert support, wherein said catalyst composition comprises 1-10 mass % lanthanum and 1-10 mass % manganese and optionally 0.3-3 mass % alkali metal.
