Abstract
A process for catalytically cracking a hydrocarbon with simultaneous production of a low BTU fuel gas and catalyst regeneration comprising contacting a hydrocarbon feed, at elevated temperature and in a cracking zone, with a solid acid catalyst comprising a catalytic metal oxide component wherein said metal is selected from the group consisting essentially of (a) tungsten, niobium and mixtures thereof (b) mixture of (a) with tantalum, hafnium, chromium, titanium, zirconium and mixtures thereof, said oxide component being supported on a silica-containing inorganic refractory metal oxide support having a silica content less than 50 wt. % of the total support, to produce a cracked product and a deactivated catalyst and regenerating the deactive catalyst to produce a low BTU gas rich in CO, a gas rich in H.sub.2, or both and recirculating the regenerated catalyst back to the cracking zone, said catalyst being steamed prior to use at a temperature at least 600.degree. C. In a preferred embodiment, the catalyst support will comprise a mixture of silica and .gamma.-alumina.
