20090165376 | Steam Generating Slurry Gasifier for the Catalytic Gasification of a Carbonaceous Feedstock - Steam generating gasification reactors for providing high-pressure and high-temperature steam for catalytic gasification of a carbonaceous feedstock can be based on oxygen blown gasification reactors adapted for processing a slurry feedstock comprising at least 40% water. The exhaust from the slurry gasifier comprises at least steam, carbon monoxide and hydrogen. The slurry composition and the oxygen to fuel ratio can be varied to control the ratio of carbonaceous gases in the generator exhaust.
