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. |
