Abstract
A process (10) for co-producing power and hydrocarbons includes in a wet gasification stage (70), gasifying coal to produce a combustion gas (86) at elevated pressure comprising at least H2 and CO; enriching (72) a first portion of the combustion gas with H2 to produce an H2-enriched gas (88); and generating power (77) from a second portion of the combustion gas. In a dry gasification stage (16), coal is gasified to produce a synthesis gas precursor (36) at elevated pressure comprising at least H2 and CO. At least a portion of the H2-enriched gas (88) is mixed with the synthesis gas precursor (36) to provide a synthesis gas for hydrocarbon synthesis, with hydrocarbons being synthesized (20, 22) from the synthesis gas. In certain embodiments, the process (10) produces a CO2 exhaust stream (134) for sequestration or capturing for further use.
