Improve sulfiding of hydroprocessing catalysts

An alternative safer, easier method to activate catalysts

Roberts, C. D., The Lubrizol Corp.

T?he catalyst in all hydroprocessing units in a refinery—hydrotreaters, hydrodesulfurizers and hydrocrackers alike—require sulfiding. Typically, a catalyst starts out in an inert/inactive form, with the active metals in the oxide form. The catalyst is sulfided by reaction of its active metals with hydrogen sulfide, which is produced in situ from a reaction between available sulfur in the feedstream and hydrogen, or more commonly from sulfur in the sulfiding agent. A defined quantity of sulfur is required to activate the catalyst. Sulfiding catalysts. There are several ways to add sulfur to the catalyst. One that may appear attractive is to use naturally occurring sulfur in the f
