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: Process and plant for producing a gasoline product from an oxygenate feed stream comprising the steps of: conducting the oxygenate feed stream to an oxygenate-to-gasoline reactor, suitably a methanol-to-gasoline (MTG) reactor, under the presence of a fixed bed of catalyst active for converting oxygenates in the oxygenate feed stream to a raw gasoline stream comprising C3-C4 paraffins and C5+ hydrocarbons; separating from the raw gasoline stream a gasoline product stream comprising the C5+ hydrocarbons and a stream comprising C3-C4 paraffins; conducting the entire stream comprising C3-C4 paraffins or a portion thereof to an upgrading reactor under the presence of a catalyst active for converting the C3-C4 paraffins into an aromatic stream such as an aromatic stream comprising benzene, toluene and xylene (BTX); and combining the entire aromatic stream or a portion thereof with the oxygenate feed stream.
