Cracking with co-matrixed zeolite and P/alumina

Patent ·
OSTI ID:5516342
A process is described for the catalytic cracking of a hydrocarbon feed which comprises: contacting the feed at catalytic cracking conditions with a catalyst comprising: (a) a crystalline metallosilicate zeolite; (b) a non-zeolitic inorganic oxide matrix, the zeolite being dispersed in the matrix, and (c) discrete particles of phosphorus-containing alumina also dispersed in the matrix, the discrete particles having been prepared by contacting alumina having a BET surface area greater than 50 square meters per gram with a phosphorus compound selected from the group consisting of phosphoric acid, a salt of phosphoric acid, phosphorous acid, a salt of phosphorous acid, and mixtures thereof, for a time sufficient to incorporate an effective amount of phosphorus in the alumina.
