SYNTHESIS GAS PRODUCTION USING AIR

摘要

A process for the production of synthesis gas characterized by: (a) partially oxidizing a carbonaceous fuel using air or oxygen enriched air, (b) reacting carbon monoxide contained in the stream from step (a) with steam, to convert the majority of the carbon monoxide to carbon dioxide and hydrogen, (c) passing the stream from step (b) through a permeable membrane separation device in which the carbon dioxide and hydrogen largely permeates through whilst the nitrogen does not (d) utilizing a catalyst to cause combustible compounds present in the non-permeate stream (c) to react exothermally to raise the temperature of the stream. The stream from step (d) may be expanded to gain shaft horsepower.
