What agent is used for catalyst presulfurization?
Thread Content
Dear teachers: I would like to ask that in the past, DMDS was used for the presulfurization of catalysts. Now, the design institute has introduced an environmentally friendly additive called FSA-55. I wonder if anyone has used it; could you please share the results of its use and compare it with DMDS? Thank you!
You’re using the catalyst formulated by the Fushun Research Institute, right? I used products from that institute before, and it was required to use the sulfiding agent you mentioned; it’s said to be more environmentally friendly. In fact, it’s just that the production process of this sulfiding agent is more eco-friendly at present. Its sulfur content isn’t as high as that of DMDS, but its price is quite high. In the end, we still chose the conventional DMDS
Thank you. We have also done our research, and many organizations use this type of agent, mainly for environmental reasons!
