摘　　要：本文采用原子吸收光谱、X射线衍射、扫描电镜、元素分析等方法分别对分子筛催化剂在催化裂化反应前后进行了表征。探讨了催化剂失活的原因,以及活化后与新鲜、失活催化剂的差别。In this paper,the characterization of the molecular sieve catalysts before and after the catalytic cracking reaction has been performed by atomic absorption spectroscopy,X- diffraction,scan electronic microscope, elemental analysis and so on. The reasons for catalysts deactivation is discussed, and difference of fresh, deactivated and regenerated catalysts is analyzed.
