摘　　要：分析了胜华炼油厂催化裂化催化剂的重金属污染情况.分析发现,除常见污染催化剂的金属镍、钒、铜、钠外,铁污染相当严重.铁对催化剂的污染不仅影响催化剂的选择性,而且高含量的铁会明显降低催化剂的微反活性.通过对原料油中的硫、氯离子和酸值的分析,从腐蚀的角度探讨了铁的来源.The analysis of the metal contamination of the FCC catalyst in shenghua Refinery forund that it is also severely contaminated by iron besides common nickel, vanadium, copper and sodium. The iron not only affects the catalyst selectivity but also reduces the catalyst microactivity at higher content. Through analysis of sulfur and chlorine ions and acid value,the sources of iron were studied.
