FIELD: chemistry.
SUBSTANCE: present invention relates to a fluid catalytic cracking process. Described is a method for cracking hydrocarbon feedstock under fluid catalytic cracking (FCC) conditions, which includes: adding one or more components with boron oxide on FCC-compatible inorganic particles to cracking particles in an FCC unit; where FCC-compatible inorganic particles are a first type of particle placed in the FCC unit, with a second type of particle having a composition different from the first type of particles; the first type of particle contains one or more components with boron oxide and a first matrix component; the second type of particle has a composition different from the first type of particles, and includes a second matrix component, and is active for hydrocarbon cracking; the first type of particle and the second type of particle are mixed together; FCC-compatible inorganic particles contain matrix material and non-zeolitic material; one or more components with boron oxide are present in an amount in the range of 0.005 to 20 % by weight of FCC-compatible inorganic particles; and cracking particles are present in the range of 60–99 wt. % and FCC-compatible inorganic particles are present in the range of 1–40 wt. %.
EFFECT: technical result is a reduced yield of hydrogen and coke for different conditions of the FCC unit and hydrocarbon feedstock.
