CATALYST FOR HYDROGENATION REFINING

摘要

PURPOSE: To produce a catalyst for hydrogenation refining improved in hydrodenitrification activity in addition to an improvement of hydrodesulfurization activity. CONSTITUTION: This catalyst for hydrogenation refining capable of improving the hydrodesulfurization activity and the hydrodenitrification activity is produced by using a fire resistant oxide consisting of silica-containing alumina and an interlaminar clay compd. such as raponite and/or saponite as a main component of its carrier. As a result, the catalyst has remarkably improved activities not only in desulfurization but also in denitrification when compared with a conventional catalyst for hydrogenation refining using an alumina carrier or a silica-containing alumina carrier. The catalyst is very useful as a catalyst for pre-hydrogenation treatment of a fluidized catalytic cracker due to improvement in the desulfurization activity.
