DEVELOPMENT OF FORMULATION DESIGN OF HEAVY OIL FCC CATALYSTS

To increase the percentage of residue in heavy oil FCC feed, improve liquid product yields and maximize light olefin and clean fuel production, a number of improvements have been made in catalyst formulations in the past several years. The major developments are: optimization of catalyst pore structure and acidity , application of small crystal molecular sieve to enhance heavy oil conversion capability, Ph modification of catalyst to improve coke selectivity, modification of matrix to improve its capability to resist detrimental metals and design of catalyst formulations based upon feedstock properties and unit conditions. The principles of technologies and associated patents are discussed.
