Abstract: Combustible gas is made by the method of the parent Specification, but the catalyst additionally includes 1 to 10% by weight of silicon dioxide. Graphite may be included in an amount 0.5 to 2% by weight. Process details, including the use of a platinum guard catalyst, are similar to those described in the parent Specification.

Abstract: The cracking of gaseous or vaporisable hydrocarbons to gases rich in olefines, e.g. ethylene and propylene is effected autothermally and flamelessly in the presence of inert, nonporous, refractory, rigidly-arranged bodies in two stages, the preheated hydrocarbon being reacted in the first stage with insufficient oxygen for complete combustion, with or without the addition of steam, in the presence of copper and/or cobalt and/or compounds thereof coated on the inert bodies and in the second stage the remaining hydrocarbons being cracked in the presence of the inert bodies. Preferably a single reactor is used, the gases passing successively through three layers of inert bodies, the middle layer only having the catalyst coating. The bodies are preferably ceramic, e.g. porcelain, sillimanite or corundum balls of 20-100 mm diameter carrying 0,05-2% by weight of catalyst which may be activated with up to 0,5-5% of cerium. Steam may be added in amounts of 5-30% by volume of hydrocarbon and oxygen 10-40%. The hydrocarbon may be ethane, propane or butane or liquid hydrocarbons boiling in the range 40-200 DEG C. and may contain up to 30% by volume of olefines. The reactants may be preheated to 300-650 DEG C.
