Abstract: The investigation was related to the distribution of acid oxygenated compounds in Liaohe atmospheric residue (LHAR) and its slurrybed cracked residue. The LHAR was hydrocracked in pilot experimental device of state key laboratory of heavy oil processing. The reaction products was separate into <500 ℃ and >500 ℃(cracked residue). LHAR was separated into four fractions, six fractions respectively, as well as LHAR slurrybed hydrocracking cracked was separated into six fractions. The date of acid number in LHAR and its fractions were determined. The results show that the acid oxygenated compounds of LHAR are mainly distributed in resin. The acid oxygenated compounds of hydrocracking cracked residue are mainly distributed in heavy aromatic and heavy resin.

摘要： 对辽河常渣及其悬浮床加氢尾油中酸性含氧化合物的分布情况进行了研究。辽河常渣在重质油国家重点实验室中试装置中进行悬浮床加氢裂化反应。反应后产物经常减压蒸馏后,分离为<500 曟馏分及>500 曟加氢尾油。采用柱色谱法将辽河常渣分别进行四组分及六组分分离,将辽河常渣悬浮床加氢尾油进行六组分分离,测定了各个组分的酸值。结果表明,辽河常渣四组分中的酸性含氧化合物主要分布在胶质中。辽河常渣六组分中,酸性含氧化合物主要分布在重芳烃中。辽河常渣悬浮床加氢尾油的六组分中,酸性含氧化合物主要分布在胶质中, 其次是重芳烃。
