摘　　要：系统研究了硫酸铵焙烧选择性脱镍工艺条件对FCC平衡剂脱镍的影响,并进一步考察了选择性脱镍处理后平衡剂分子筛保留度、活性恢复程度以及高倍放大下平衡剂微球表面的微观形貌。实验结果表明,硫酸铵焙烧处理对平衡剂具有良好的脱镍效果,经处理后的平衡剂中Y型分子筛的晶相结构、孔道的畅通性以及微观形貌都显著改善,活性得到明显恢复。The process condition for selective removal of nickel from FCC equilibrium catalyst by calcination with ammonium sulfate was studied. Zeolite conservation, activity recovery and superficial microtopography of the treated equilibrium catalyst were investigated. The results showed that removal of nickel in FCC equilibrium by calcination with ammonium sulfate had good activity regeneration results, with remarkable improvement on crystal structure of Y zeolite, smoother pore passage and better surface microtopography.
