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 hydro-, gasification reactor under conditions whereby methane rich producer gases are generated and fed into a steam pyrolytic reformer under conditions whereby synthesis gas comprising hydrogen and carbon monoxide are generated. A portion of the hydrogen generated by the steam pyrolytic reformer is fed through a hydrogen purification filter into the hydro-gasification reactor the hydrogen …

Why it's free to use
- Filed February 4, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 4, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 4, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
