ABSTRACT:
Combustible gases containing both methane and hydrogen, for example gases obtained by the non- catalytic hydrogenation of oil or coal are treated to increase their calorific value by removal of elementary hydrogen in the catalytic hydrogenation of an unsaturated compound such as benzene. The benzene is regenerated by dehydrogenation, usually catalytic dehydrogenation, and recycled for further use. The hydrogen produced on dehydrogenation may be employed for hydrodesulphurisation or as hydrogenating gas in a non- catalytic hydrogenation stage.
