考察了热转化反应条件对胜利和孤岛渣油热转化产品中硫分布的影响。在研究原料中硫、硫醚硫、噻酚硫分布和残炭分布的基础上，探讨了原料硫分布与热转化产品中硫分布的关系。结果表明，在定时（６０ｍｉｎ）热反应条件下，随着温度的升高（４６０～５４０℃），胜利减压渣油热转化产物（馏出物、焦和气态产物）中的硫含量及分布变化不大，且焦的硫含量低于原料硫含量；而孤岛减压渣油热转化产物中的硫含量及分布变化较大，其焦的硫含量高于原料硫含量。这样的差异是由其原料中硫类型分布和残炭分布的差异引起的，渣油重组分中硫和噻酚硫含量高，残炭含量低，则所生焦的硫含量就高。
The effects of thermal conversion reaction conditions on the sulfur distribution in Victory and island residue thermal conversion products were investigated. On the basis of studying the distribution of sulfur, thioether sulfur, thiophenol and residual carbon in raw materials, the relationship between the distribution of sulfur in raw materials and the distribution of sulfur in the thermal conversion products was discussed. The results showed that the sulfur content and distribution in the thermal conversion products (distillate, coke and gaseous products) of Shengli vacuum residue increased with the increase of temperature (460 ~ 540 ℃) Little change, and the sulfur content of the coke is lower than the sulfur content of the raw material. However, the content and distribution of sulfur in the thermal conversion products of the island vacuum residue vary greatly, and the sulfur content of the coke is higher than the sulfur content of the raw material. This difference is caused by the difference in the distribution of sulfur types and the distribution of residual carbon in the raw materials. The sulfur and thiophenol sulfur content in the heavy oil residue is low, and the residual carbon content is low, the sulfur content in the resulting coke is high.
