ABSTRACT:
A method for combined cycle electrical power generation comprises utilizing a coal hydrogenator 2 and a reactor 1 for producing from a methane-rich gas a hot crude hydrogen-containing gas which is fed directly (apart from an optional quenching stage) to the coal hydrogenator. The coal hydrogenator produces gaseous and liquid products which are combusted to drive a gas turbine 5 which drives an electrical generator 6. The hydrogenator also produces char which is combusted in a boiler 10 to form steam to drive a steam turbine 11 which, in turn, drives another electrical generator 12. Such direct use of the hot crude gas avoids having to preheat hydrogen-containing feed to the hydrogenator.
