FIELD: chemistry.
SUBSTANCE: fluid catalytic cracking (FCC) compositions, cracking methods are described. Catalyst composition comprises a first particle type comprising one or more boron oxide components and a first matrix component, wherein the first particle type not including zeolite, and a second particle type having a composition different from the first particle type, the second particle type comprising a second matrix component, phosphorus component and 20 % to 95 % by weight of the catalyst composition of a zeolite component, wherein the first particle type and second particle type are mixed together.
EFFECT: fluid catalytic cracking catalyst compositions can be used to crack hydrocarbon feeds, particularly residues feeds containing high V and Ni, resulting in lower hydrogen and coke yields.
