PROCESS FOR THE CONVERSION OF OXYGENATES TO GASOLINE

摘要

A process for the preparation of hydrocarbon products, com-prising the steps of (a) providing a stream containing oxygenates; (b) mixing the said stream with a recycle stream to form a gasoline feed stream; (c) contacting the gasoline feed stream with one or more gasoline synthesis catalysts to obtain an effluent stream comprising higher hydrocarbons boiling in the gasoline range; (d) withdrawing from step (c) the effluent stream; and (e) splitting a part of the effluent stream to form the re-cycle stream which is optionally further reduced in content of water or enriched in hydrogen, then pressurised and re-cycled to step (b).
