Feasibility of directly adding pure sulfur to hydrocracking feedstock to supplement sulfur
Thread Content
The VGO used as feedstock for hydrocracking has a low sulfur content, and the hydrogen sulfide concentration in the recycle hydrogen is also low; these conditions do not meet the requirements of the catalysts, so sulfur supplementation is necessary. Moreover, vulcanizing agents are expensive and consume a large amount. Consider whether high-purity sulfur can be dissolved in hot feed oil or what pretreatment measures can be taken to prepare sulfur-rich blending feedstocks I would appreciate it if experts could provide analysis or share their practical experience to determine whether this approach is feasible Are there any harms and disadvantages?
Mr. Niu Jiali from Baotailong in Qitaihe, Heilongjiang, has a paper on Baidu Wenku that specifically introduces this solution.
It shouldn’t be possible, right? If it were possible, it would be very cheap. Looking forward to higher education. . .

http://wenku.baidu.com/view/08992d6ea45177232f60a2bc.html It seems that many people are interested in sulfur supplementation. There are two concerns with this method: first, sulfur must be kept warm; otherwise it will solidify ； Secondly, it needs to be added to the circulating oil; the amount is difficult to control, and if refining and cracking are separated, refining becomes another issue. I, being rather incompetent, am currently working on a plan to directly supplement hydrogen sulfide. Those who are interested please send an email to wangseeyou@163.com. First, please provide an overview of your company, and I will discuss the matter with you.

It would be better for you to do some theoretical work first before putting it into practice; after all, this method has never been used before, so its effectiveness is unknown.
