METHOD FOR MAKING A HYDROPROCESSING CATALYST

摘要

The present invention is directed to a method for making a catalyst for hydroprocessing a carbonaceous feedstock under hydroprocessing conditions. More particularly, the present invention is directed to methods for inhibiting rapid decomposition of ammonium nitrate during calcination of the catalyst following metal impregnation, wherein ammonium nitrate is formed when a nitrate-containing composition and an ammonium-containing component is used in the deposition of metal onto the catalyst.
