摘要： 利用固定床连续加氢处理装置，获得经过保护剂、脱金属剂、脱硫剂和脱氮剂处理的系列渣油加氢处理生成油，分析原料和各生成油中沥青质的性质，并计算沥青质组分的平均相对分子质量和稳定性参数。结果表明，随着加氢深度的增加，渣油加氢生成油沥青质中碳、氢、硫、氮、镍、钒、铁的质量分数降低，沥青质的平均相对分子质量明显降低，渣油胶体的稳定性不断降低。

Abstract: Hydrotreated oil samples from guard catalyst zone, HDM，HDS and HDN zones were collected respectively from a fixed-bed hydrotreating device. The properties of asphaltenes from residue feedstock and the obtained samples were analyzed, as well as the average molecular weight of asphaltenes and the stability parameter of residue colloidal was calculated. Results showed that with the increase of hydrotreating severity, the C，H，S，N，Ni，V and Fe contents in the asphaltenes of treated oil samples decreased significantly, the average molecular weight of asphaltenes and the stability parameter of residue colloidal decreased as well.
Key words: asphaltenes, petroleumresidue, hydrogenation, character, study method
