The invention relates to a preparing method of a rare earth catalytic cracking double-metal deactivator. The method includes steps of: A) mixing 300-600 kg of a mother liquor A, 50-150 kg of a mother liquor B and 5-20 kg of a pH conditioner and stirring; and B) adding 30-80 kg of deionized water, stirring for 30-60 min and discharging. The catalytic cracking double-metal deactivator with wide suitability is developed, thus effectively solving a suitability problem of deactivators. |
