Claims
- 1. A method for the catalytic cracking of hydrocarbons which comprises reacting a hydrocarbon in the presence of a catalyst which comprises a zeolite-containing cracking catalyst admixed with a composition comprising discrete particles of a rare-earth compound selected from the group consisting of rare-earth oxalate, oxide, oxychloride and mixtures thereof dispersed in a clay/alumina matrix under catalytic cracking conditions.
- 2. The method of claim 1 wherein the matrix comprises clay and alumina derived from aluminum hydroxychloride sol.
- 3. The method of claim 1 wherein the matrix includes silica-alumina hydrogel.
- 4. The method of claim 1 wherein the rare-earth component comprises about 5 to 60 weight percent La, Nd and mixtures thereof expressed as the oxide.
- 5. The method of claim 1 wherein the catalyst and composition have a particle size of 10 to 150 microns.
- 6. The method of claim 1 wherein the hydrocarbon contains vanadium.
- 7. The method of claim 1 wherein the hydrocarbon contains nickel and vanadium.
- 8. The method of claim 6 wherein the catalyst contains up to 10,000 to 20,000 ppm vanadium.
