Abstract
The present invention relates to a method of removing sulfur from a hydrotreating process stream comprising contacting a sulfur containing feedstock with a stacked bed catalyst system comprising a first catalyst bed comprising hydrodesulfurization catalysts followed by a second catalyst bed comprising ruthenium sulfide having a surface area of at least about 30 m.sup.2 /g and wherein said hydrodesulfurization process is conducted at a temperature of about 150.degree. C. to about 400.degree. C. and a pressure of about 50 psig (344.74 kPa) to about 2500 psig (17236.89 kPa).
