Process for the production of acetic acid ethylene and vinyl acetate monomer

A process for the preparation of hydrocarbon products including the steps of (a) providing a stream containing oxygenates; (b) mixing the 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 with 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 recycle stream which is optionally further reduced in content of water or enriched in hydrogen, then pressurized and recycled to step (b).

A process for the adjustment of the composition of a synthesis gas produced in a high temperature black liquor gasifier.
