Abstract
A process () for co-producing power and hydrocarbons includes gasifying () coal to produce a synthesis gas () and a combustion gas () both comprising at least COHand COand being at elevated pressure, separating CO() from the synthesis gas, and synthesizing () hydrocarbons from the synthesis gas. Power () is generated from the combustion gas, including by combusting () the combustion gas in the presence of oxygen and in the presence of at least a portion of the separated CO2 as moderating agent to produce a hot combusted gas () which includes CO. The CO2 is recycled () or recovered from the combusted gas. In certain embodiments, the process () produces a COexhaust stream () for sequestration or capturing for further use.
