Abstract: A four stage steam reformer suitable for producing a synthetic gaseous stream from a carbonaceous feedstock. Each stage is capable of operating at a progressively higher temperature than the immediate preceding stage.

Abstract: A process for substantially increasing the production of ethanol from corn and other such biomass feedstocks. Ethanol, carbon dioxide and distiller grains are typically produced during the fermentation process. The carbon dioxide is used as a feed for additional ethanol make and the distiller grains can be used as a livestock feed or to produce a synthetic fuel gas that is used to run a boiler to produce steam used in the fermentation process.

Abstract: An integrated process wherein a CO2-free fuel gas is produced from steam reforming a carbonaceous material and sent to a gas turbine which is associated with an electrical generator. The CO2 produced during the steam reforming of the carbonaceous material is passed to a second steam reforming zone where it is mixed with a second carbonaceous feed to produce a syn-gas that is used to produce ethylene.

Abstract: A process for generating electrical power from a carbonaceous fuel source without carbon dioxide emissions while producing ethanol. A carbonaceous material is reacted in a stream reformer wherein a fuel gas is produced, which fuel gas is sent to a CO shift reactor to convert substantially all CO to CO2 thus resulting in a CO-lean fuel gas stream. The CO-lean fuel gas stream is sent to an acid gas recovery zone to produce a hydrogen rich stream which is sent to a gas turbine associated with an electrical generator. The acid gas stream, of which H2S is removed, thus leaving CO2 which is sent to a second steam reforming zone along with a second carbonaceous feedstock wherein a syn-gas stream is produced which is eventually converted to ethanol.
