Abstract:
1. A method for generating power from carbonaceous material, comprising: boiling water into steam; reforming the carbonaceous material with the steam to generate a high-pressure gas comprising carbon dioxide gas and hydrogen gas, wherein sufficient steam is provided to ensure a substantial majority of the carbonaceous material is converted into carbon dioxide gas and hydrogen gas; exchanging heat from hot gas exiting the reforming step with the steam entering the reforming step; separating at least a portion of the carbon dioxide gas from the high-pressure gas to generate a carbon dioxide-rich gas and a hydrogen-rich gas; utilizing the carbon dioxide-rich gas in an industrial process; and generating power in a power generation system from a portion of the hydrogen-rich gas, wherein waste heat from the power generation system is used to provide heat to the boiling water step.
