Abstract
A process is provided for converting feedstock hydrocarbon compounds over a catalyst composition which comprises clay and a zeolite component, at least one of which has been treated with a phosphorus-containing compound, for example, ammonium dihydrogen phosphate or phosphoric acid, and which is spray dried at a low pH, preferably lower than about 3. An embodiment of the present invention comprises an improved catalytic cracking process to produce high octane gasoline and increased lower olefins, especially propylene and butylene.
