Abstract

Temperature-programmed sulfiding, TPD, and TPR of ammonia were applied to characterize six commercial hydroprocessing catalysts. In addition, their chemical composition, surface area, pore volume, and major crystalline phase were also determined. HDS of benzothiophene in a pulse-type micro reactor was performed to evaluate the HDS activity of the catalysts. Catalysts that were reduced at lower temperature performed better in terms of HDS of benzothiophene. Hydrocracking of cumene was studied to evaluate the cracking ability of the catalysts. The cracking activity of the catalysts was very well correlated with the acidity. TPS patterns of the Mo containing catalysts were similar with each other. However, W containing catalyst showed a different sulfiding behavior. This approach could be utilized for the fast screening of commercial hydroprocessing catalysts and also for finding the best promising laboratory prepared catalysts. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
