渣油中硫化物的测定方法研究进展

Research Development on the Methods to Determine Sulfer Compounds of Residue

渣油中硫化物的存在对石油加工和石油生产带来很多不利条件,渣油中的主要硫化物为硫醚硫和噻吩硫,总硫与硫醚硫的差值即为噻吩硫。对硫化物定量研究,可以为渣油加工提供理论依据和数据基础。本文概述了渣油中硫醚硫的测定方法,并对各种方法的优缺点进行了讨论,在实际应用中应结合实际条件选择合适的方法对硫化物进行研究。

The sulfur-containing compounds in residues have negative effects on residue processing. The sulfur compounds in residues are mainly composed of thioethers and thiophenes. In general, thioethers content is determined by certain method and thiophenes content is obtained from differences between total sulfur content and thioethers content. The quantitative study of the two kinds of sulfer compounds can provide theoretical and technical supports for residual processing, The methods of determine sulfer compounds of residue were mentioned in the paper. And the advantages and disadvantages were also discussed. We should select suitable methods according to different conditions.
