Steam pyrolysis as a process to enhance the hydro-gasification of carbonaceous materials

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. In one embodiment, a slurry of carbonaceous material in water, and hydrogen from an internal source, are fed...

Beschreibung
Zusammenfassung:	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. In one embodiment, a slurry of carbonaceous material in water, and hydrogen from an internal source, are fed into a hydro-gasification reactor to generate methane rich producer gases which are fed into a steam pyrolytic reformer to generate synthesis gas comprising hydrogen and carbon monoxide. A portion of the hydrogen is used as the internal hydrogen source. The remaining synthesis gas is either used as fuel to produce electricity and/or process heat or is fed into a Fischer-Tropsch reactor to produce liquid fuel. In another embodiment of the invention, carbonaceous material can be heated simultaneously in the presence of both hydrogen and steam to undergo steam pyrolysis and hydro-gasification in a single step.
