Patent ID: 8603430

Claim:
A method of processing a methane containing gas from a steam-hydrogasification reactor to thereby form a syngas, comprising: feeding hydrogen and an aqueous slurry of water and a carbonaceous material to a steam-hydrogasification reactor; operating the steam-hydrogasification reactor at a pressure and under conditions effective to form steam from the slurry to thereby, with the hydrogen, form a methane-containing product gas; feeding the methane-containing product gas into an autothermal methane reformer, and subjecting the methane-containing product at the pressure to a reforming reaction to thereby form a hydrogen-enriched product gas; condensing steam from the hydrogen-enriched product gas at the pressure to thereby form a dehydrated hydrogen-enriched product gas; and removing sulfur compounds at the pressure from the dehydrated hydrogen-enriched product gas to thereby form the syngas.
