Patent ID: 6976362

Claim:
A process comprising: introducing a carbonaceous raw material, water and oxygen into a syngas generator under syngas forming operating conditions to form a syngas; introducing a portion of the syngas into a Fischer-Tropsch reactor and forming primarily aliphatic hydrocarbons and carbon dioxide; separating liquid hydrocarbons from the carbon dioxide, unconverted carbon monoxide, and hydrogen, which are Fischer-Tropsch tail gases; introducing a portion of the syngas along with water and the Fischer-Tropsch tail gases into a water-gas-shift reactor to produce primarily hydrogen and carbon dioxide; scrubbing the carbon dioxide from gases emitted from the shift reactor using a CO 2 scrubber; collecting the carbon dioxide for sale or sequestration; and burning the gases rich in hydrogen from the CO 2 scrubber in a gas turbine combustor of a combined cycle plant to drive a generator mechanically coupled to the gas turbine during a production of electricity.
