Abstract
Supported ruthenium metal catalysts prepared by reduction of carbonyl compounds give improved yields of methane in the hydro-cracking of hydrocarbons, especially alkanes and alkyl aromatics. Alkanes may be cracked to methane at low temperature (200.degree.-300.degree. C.) and the de-alkylation of alkyl benzenes may be controlled sufficiently to allow removal of isomers e.g. ethylbenzene from xylenes. The novel catalysts comprise ruthenium clusters having average dimensions below 20 A.
