Abstract: The present application relates to a process for production of hydrocarbons comprising the steps of converting a feed stream comprising alcohols, ethers or mixtures hereof over a metal-containing zeolite based catalyst, active in dehydrogenation of hydrocarbons, in a conversion step thereby obtaining a conversion effluent, separating said effluent to obtain art aqueous process condensate stream, a liquid hydrocarbon stream and a gaseous stream, removing part of the hydrogen formed in the conversion step, and recycling at least part of the gaseous and/or liquid hydrocarbon stream to the conversion step.

Abstract: In a process for the catalytic conversion of lower hydrocarbons to aromatic compounds comprising benzene, toluene and xylenes, a process stream containing lower hydrocarbons is contacted with a zeolitic catalyst having an MFI framework and containing 0.1 to 10 percent by weight of a zinc compound. The process stream further contains one or more sulfur compounds, especially hydrogen sulfide, for improving the selectivity.
