摘要： PCA-101环保型多功能助剂在中国石油呼和浩特石化公司2.80 Mt/a催化裂化装置上进行了工业应用。结果表明：加注PCA-101环保型多功能助剂后，不会对装置在用催化剂造成污染；平衡剂中锑质量分数由2 425 μg/g降低至716 μg/g，实现废催化剂由危险废物向固体废物的转变；轻油收率提高0.49百分点，有效改善产品分布；干气中氢气体积分数从48.92%下降至47.39%，具有良好的抑制Ni污染效果。

Abstract: Environment-friendly multifunctional additive PCA-101 was used in the 2.80 Mt/a catalytic cracking unit of PetroChina Huhhot Petrochemical Company. The results showed that the addition of PCA-101 did not cause pollution to the catalyst in the FCC unit. The antimony content in the equilibrium catalyst was reduced from 2 425 μg/g to 716 μg/g, and the waste catalyst was transformed from the dangerous waste to the solid waste. Moreover, the yield of light liquid increased by 0.49 percentage point, which effectively improved the product distribution. The volume fraction of hydrogen in dry gas decreased from 48.92% to 47.39%, which indicated that PCA-101 had a good effect of inhibiting Ni pollution.
Key words: catalytic cracking, multifunctional additive, antimony, nickel, hydrogen
