FKK CATALYTIC COMPOSITIONS CONTAINING BORON OXIDE AND PHOSPHORUS

摘要

Described are fluid catalytic cracking (FCC) compositions, methods of manufacture and use. FCC catalyst compositions comprise particles first particle type comprising one or more boron oxide components and a first matrix component and a second particle type having a composition different from the first particle type, the second particle type comprising a second matrix component, a phosphorus component and 20% to 95% by weight of a zeolite component. The FCC catalyst compositions can be used to crack hydrocarbon feeds, particularly resid feeds containing high V and Ni, resulting in lower hydrogen and coke yields.
