以克拉玛依炼油厂常压渣油为原料,在重质油加氢实验室中试装置进行悬浮床加氢反应:反应时间为1h,催化荆质量分数为800 μg/g,反应温度分别为410,430,440℃.对反应后产物进行常减压蒸馏.采用柱色谱法对克炼常渣及其悬浮床加氢尾油进行四组分分离,测定了各组分的酸值,考察了常压渣油及其悬浮床加氢尾油中酸性含氧化合物的分布情况.研究结果表明,克炼常渣中的酸性含氧化合物主要分布在胶质中；克炼常渣悬浮床加氢尾油中的酸性含氧化合物主要分布在胶质和沥青质中.%Karamay atmospheric residue(KLAR) was hydrocracked in pilot experimental device of state key laboratory of heavy oil processing, with the presence of an oil - soluble catalyst. Reaction time was set to 1 h and reaction catalyst concentration at 800 μg/g, reaction temperature were 410,430 and 450 ℃. Then KLAR and its slurry-bed hydrocracking cracked residue were separated into four fractions. The acid number in each fraction was determined. The distribution of the acid oxygenated compounds in each material was obtained. The results show that the acid oxygenated compounds in KLAR are mainly distributed in resin, which in slurry-bed hydrocracking cracked residue of KLAR are mainly distributed in resin and asphaltene.
