渣油中总硫及硫化物分析测定方法研究进展

Research Progress in Determination Methods of Total Sulfur and Sulfer Compounds of Residue

渣油中硫化物的存在对石油加工和油品性能产生诸多不利影响。综述了渣油中总硫、硫醚硫和噻吩硫的测定方法及其应用,并对各种方法优缺点进行了分析讨论。对渣油中硫化物组成和结构进行定量和定性分析,将对进一步研究和选择合理的渣油深加工方案提供理论依据和数据支持。

The sulfur-containing compounds in residue have many adverse effects on the oil processing and oil properties. In this paper,the methods to determine the total sulfur and sulfer compounds of residue were reviewed. And their advantages and disadvantages were also analyzed and discussed. The quantitative and qualitative analysis of composition and structure of the sulfide in the residue can provide theoretical basis and data supports for further research and selection of reasonable residue deep processing scheme.
