Abstract

The present application relates to a hydrogenation catalyst, a process for producing the same and application thereof in the hydrotreatment of feedstock oil. The process comprises at least the following steps: (1) contacting a first active metal component and a first organic complexing agent with a carrier to obtain a composite carrier; (2) calcining the composite carrier to obtain a calcined composite carrier having a total carbon content of 1% by weight or less; and (3) contacting a second organic complexing agent with the calcined composite carrier to obtain the hydrogenation catalyst. The hydrogenation catalyst has both excellent hydrodesulfurization activity and hydrodenitrogenation activity, and exhibits a significantly prolonged service life.
