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 temperatures (200-300 DEG 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 ANGSTROM .
