The distribution and transfer of sulfide in the thermal reaction process are studied. It has found that different types of sulfur have different distribution patterns in the refining process. Thiophene derivatives with better thermal stability are mainly distributed in the heavy components, while mercaptans and small molecular thioethers with poor thermal stability are mainly distributed in the light components. During the thermal reaction, part of the sulfide will decompose or react to produce sulfide with a smaller molecular weight, which will be transferred to light components or gases. The thermal reaction temperature has a certain effect on the product yield and sulfur content. As the reaction temperature increases, the liquid yield increases and the sulfur content decreases, but the thermal reaction temperature has little effect on the sulfide type distribution.
