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.

Process and plant for converting oxygenates to gasoline with improved gasoline yield and octane number as well as reduced durene levels

A production plant and a method for production of a synthetized gasoline product from a synthetic hydrocarbon mixture produced from a mixture of reactive oxygenates, the method including a. separating the synthetic hydrocarbon mixture in at least a light hydrocarbon fraction, and a higher boiling hydrocarbon fraction, wherein the higher boiling fraction comprises at least 70% of the molecules including 10 or more carbon atoms and less than 20% of the molecules comprising exactly 9 carbon atoms, b. directing at least an amount of said higher boiling hydrocarbon fraction as a hydrocracking feedstock to contact a material catalytically active in hydrocracking under effective hydrocracking conditions providing a hydrocracked hydrocarbon stream, wherein at least an amount of said hydrocracked hydrocarbon stream is combined with at least an amount of said light hydrocarbon fraction, to provide said synthetized gasoline product having a Tbeing below Tof said synthetic hydrocarbon mixture.
