| Summary: | The properties of a FCC catalyst additive prepared from Guizhou kaoline were extensively investigated. The samples were characterized by N<sub>2 adsorption, X-ray diffraction, IR spectrometry, and scanning electron microscope (SEM). The results showed that the crystallinity of NaY zeolite synthesized from this kaoline was 25% and the silica alumina ratio was <sub>rk/s ˇ m </sub>= 5.05. The catalyst additive prepared from above crystallization product exhibited excellent performance of nickel and vanadium passivation, offered 21% lower coke versus base catalyst, while maintaining high bottoms upgrading selectivity. |
