| 摘 要： | 选择Ａｌ和Ｐ元素作为催化裂化催化剂的钝镍组分，并用裂化反应产物中氢气含量、微活指数（ＭＡＴ）、积炭量等指标对元素Ａｌ和Ｐ的钝镍效果进行了考察。结果表明，Ａｌ和Ｐ均能降低裂化反应产物中的氢气含量，Ａｌ能提高催化剂的裂解活性，而Ｐ能减少催化剂上的积炭。因此，Ａｌ和Ｐ对抑制Ｎｉ污染都有明显效果。

| Abstract: | Al and P are added to FCC catalyst as nickel passivation agents, and the properties of catalysts including microactivity test (MAT)indexes, the concentration of H 2 and coking amount are investigated. It is observed that the hydrogen in reaction gas is reduced, and the cracking activity of catalyst increased. There is a stable compound produced by the reaction between Ni and Al or P, which can surpress the reductivities of nickel species. So Al and P can dramatically mitigate the deletrious dehydrogenation effects of contaminant metal nickel in FCC catalysts. |
