Sulfiding agent decomposition temperature has little catalyst effect
1987
Pilot plant tests, sponsored by Gaylord Chemical Co., Houston, have been conducted at the University of Pittsburgh Applied Research Center (PARC) to directly compare dimethylsulfide (DMS) and dimethyldisulfide (DMDS) for sulfiding distillate desulfurization catalysts. Results indicate that if the agents are used with a reasonable feedstock, only under very special circumstances will the decomposition temperature have any effect on carbon laydown, catalyst sulfur uptake, or catalyst activity. This article explains the tests and the results.
