摘　　要：对克拉玛依常压渣油在悬浮床加氢裂化中试装置上得到的残渣油中的固体物质进行了X射线衍射、激光拉曼光谱和X射线光电子能谱分析。对固体物质的存在形态有了较清晰的认识 :固体物质为反应过程中形成的分散型催化剂和焦炭 ;催化剂的活性态为非化学计量的金属硫化物 ,焦炭为高度缩合的稠环芳烃并有部分石墨化结构出现 ;The solid matter in hydrocracking residual oil of kalamayi atmospheric residual oil was analyzed by X-ray diff raction(XRD),laser Raman spectroscopy(LRS) and X-ray photoelectron spectroscopy (XPS).The results showed that the solids were dispersed catalyst and coke formed during the reaction,the active catalytic species of dispersed phase Fe catalyst was FeS 1-x .The coke was highly condensed aromatic/graphitic structure.The catalyst was packed tightly by the coke and lost activity.
