Abstract: Process for converting an oxygenate feed stream, the process comprising the steps of: conducting the oxygenate feed stream to an oxygenate-to-gasoline reactor, suitably a methanol-to-gasoline reactor (MTG reactor) under the presence of a catalyst active for converting oxygenates in the oxygenate feed stream into a raw gasoline stream comprising C3-C4 paraffins and C5+ hydrocarbons; and adding an aromatic stream to the MTG reactor.

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.

Abstract: A bifunctional catalyst for example for conversion of oxygenates, the bifunctional catalyst comprising zeolite, alumina binder, Zn and P, wherein Zn is present at least partly as ZnAl2O4.
