FIELD: metallurgy.
SUBSTANCE: present invention relates to a method of passivating and/or trapping at least one metal impurity from a liquid oil product in cracking apparatus on fluidised catalyst, comprising: contacting said liquid oil product, which contains at least one metal impurity, with a catalytic mixture containing 1) cracking catalyst on fluidised catalyst and 2) metal passivator/trap, which contain mixed metal oxide alloy of R, Sb, and optionally M, where R is Fe2+/3+ and M is an optional activator.
EFFECT: technical result is increased output of end products (selectivity with respect to transport fuel) due to reduced effect of catalyst deactivation by means of metal impurities in liquid oil products.
