Abstract: Vaporizable hydrocarbons boiling in the range 30 DEG to 200 DEG C are catalytically cracked with steam at 600 DEG to 950 DEG C. in the presence of a calcined catalyst comprising nickel, magnesium oxide and aluminium oxide. Gasoline fractions may thus be cracked at pressures up to 40 atmospheres, without catalyst decomposition or carbon deposition. Excess steam may be used, e.g. 4 to 5 moles steam per gram atom of carbon at pressures above 5 atmospheres. The catalyst may comprise, percentages by weight, 10 to 30% Ni, 10 to 70% MgO, and 10 to 65% Al2O3, and calcining is at over 1050 DEG C., e.g. 1100 DEG to 1250 DEG C. Two specific examples are described, including the compositions of the methane-containing gases produced.
