A circulating oxygen uptake test was used to study the Daqing medium lube oil with respect to the interaction between sulfur-containing compounds and different aromatic components, the effective factors which affect the oxidation stability, and the effect of sulfur-containing compounds on the kinetic oxidation reaction curves of the sample.

A circulating oxygen uptake test was used to study the Daqing medium lube oil with respect to the interaction between sulfur-containing compounds and different aromatic components, the effective factors which affect the oxidation stability, and the effect of sulfur-containing compounds on the kinetic oxidation reaction curves of the sample. The research leads to the conclusions as follows: Synergism of dinuclear and polynuclear aromatics with sulfur-containing compounds is the effective factor to the oxidation stability of the lube oil. The higher the content of dinuclear and polynuclear aromatics as well as sulfurcontaining compounds, the greater this synergism, while interaction of mononuclear aromatics and sulfur-containing compounds changes from synergism to antagonism as sulfur content increases. The main sulfur-containing compounds in the lube oil are thiophenic compounds and sulfides. The kinetic oxidation reaction curves of the oil are independent of the content of thiophenic compounds but dependent on that of sulfides. The cyclosulfide and disulfide are more effective than the other sulfides. Antioxidation of the oil is closely connected with the sulfur content in oil. When the sulfur content is low, oxidation can be inhibited by sulfur-containing compounds in the later stage of oxidation.Only when the sulfur content in the oil reaches a certain value,sulfur-containing compounds exert significant antioxidation during the whole oxidation process.

以大庆中质润滑油基础油为试油,采用循环吸氧方法,研究了含硫化合物与芳烃各组分的相互作用,考察了影响油品氧化安定性的有效因素,并探讨了含硫化合物对大庆油氧化动力学曲线的影响。结果表明:双环芳烃和多环芳烃与含硫化合物的增效作用是油品的抗氧有效因素;润滑油中硫化物主要是噻吩型和硫醚型,硫醚型硫化物具有抗氧活性,环硫醚和二硫化物活性更强;含硫化合物的抗氧能力与其在油中的含量密切相关,只有当硫含量达到一定值时,才能在整个氧化过程中发挥显著的抗氧化作用.

Abstract In order to improve the capability of the vacuum tower of the crude oil distillation unit and to meet the needs of lube oil basestock production, Dongfanghong Refinery with the cooperation of Beijing Graduate Department of East China Petroleum College has taken a technical innovation to the vacuum tower of the third crude unit in the refinery. To doing this, the software Model MIRT-1 developed by the Graduate Department was used in design work. Performance test was taken place after revamping, showing that the innovation was successful and the quality of the base oils thus produced was improved with an increase in capacity.
