A method of treating a gaseous mixture comprising hydrogen and carbon dioxide

摘要

Hydrogen (H 2 ) gas is separated from a gaseous mixture of hydrogen and crude carbon dioxide (CO 2 ) gas. Combustible gas(es) in the crude CO 2 gas are combusted to produce heat, at least a portion of which is recovered by indirect heat exchange with at least a portion of the separated H 2 gas or a gas derived therefrom. The invention may be integrated with coal-fired power stations to reduce or eliminate emission of harmful components into the atmosphere.
