In hydroprocessing units, catalyst wetting is used to establish uniform flow of feed in the catalyst bed as well as uniform coverage of feed over all the catalyst prior to in-situ sulfidation. Many catalysts exhibit a wetting exotherm due to heat of adsorption which passes through the catalyst system during this step.
Using Eurecat's Totsucat pre-activated catalyst eliminates the need for in-situ sulfidation, including the catalyst wetting step.
