The study of passivation of nickel and vanadium on FCC catalyst by modified aluminaand ABO3, a synthesized complex oxide, showed that the matrix of FCC catalyst containing modified alumina and ABO, posseses high metal tolerance ability.

• 为解决原料油中镍和钒对FCC催化剂的污染，研制了用磷改性的活性氧化铝和一种金属复合氧化物ABO3，将它们按一定比例加到流化催化裂化（FCC）催化剂基质中，对其改性。
