Preparation and Cracking Performance of FCC Co-Catalyst for Enhancing Light Oil Production

在这篇论文，为提高轻采油的 FCC 合作催化剂被大音阶的第五音胶化方法准备，并且它击碎催化剂的残余的表演上的效果在结果显示了的 CCFFB reactor.The 测试被评估液体产品收益显然增加了，在 FCC 平衡催化剂的表面与干燥气体的 co-catalyst.The 收益被使妊娠以后，泥浆和焦炭减少了，当柴油机收益改变了 slightly.And 时残余的 crackability 被增加；催化剂表面上的焦炭免职的率被减少，与这些结果显示出的热裂开反应 inhibited.All 合作催化剂能改进酸地点的密度并且改变催化剂酸味，它能支持由在 FCC 平衡催化剂的表面上扔合作催化剂延长催化剂活动。

In this paper, a FCC co-catalyst for enhancing the light oil production was prepared by the sol-gel method, and its effect on the performance of residue cracking catalysts was evaluated in a CCFFB reactor. The test results indicated that the liquid product yield increased obviously, after the surface of FCC equilibrium catalyst was impregnated with the co-catalyst. The yields of dry gas, slurry and coke decreased, while the diesel yield changed slightly. And the crackability of residue was increased; the rate of coke deposition on catalyst surface was decreased, with the thermal cracking reactions inhibited. All these results showed that the co-catalyst could improve the density of acid sites and change the catalyst acidity, which could promote to prolong the catalyst activity by depositing the co-catalyst on the surface of FCC equilibrium catalysts.
