PRODUCTION OF SYNTHETIC TRANSPORTATION FUELS FROM CARBONACEOUS MATERIALS USING SELF-SUSTAINED HYDRO-GASIFICATION

摘要

A process and apparatus for producing a synthesis gas for use as a gaseous fuel or as feed into a Fischer-Tropsch reactor to produce a liquid fuel in a substantially self-sustaining process. A slurry of particles of carbonaceous material in water, and hydrogen from an internal source, are fed into a hydr o- gasification reactor under conditions whereby methane rich producer gases ar e generated and fed into a steam pyrolytic reformer under conditions whereby synthesis gas comprising hydrogen and carbon monoxide are generated. A porti on of the hydrogen generated by the steam pyrolytic reformer is fed through a hydrogen purification filter into the hydro-gasification reactor, the hydrog en therefrom constituting the hydrogen from an internal source. The remaining synthesis gas generated by the steam pyrolytic reformer is either used as fu el for a gaseous fueled engine to produce electricity and/or process heat or is fed into a Fischer-Tropsch reactor under conditions whereby a liquid fuel is produced. Molten salt loops are used to transfer heat from the hydro- gasification reactor, and Fischer-Tropsch reactor if liquid fuel is produced , to the steam generator and the steam pyrolytic reformer.
