Abstract

Official abstract text for this publication.

The present invention provides a method for producing a hydroprocessing catalyst including a supporting step of allowing a catalyst support having a content of a carbonaceous substance containing carbon atoms of 0.5% by mass or less in terms of carbon atoms to support an active metal component containing at least one active metal element selected from metals belonging to Group 6, Group 8, Group 9 and Group 10 in the periodic table, to obtain a catalyst precursor, and a calcining step of calcining the catalyst precursor obtained in the supporting step to obtain the hydroprocessing catalyst.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a hydroprocessing catalyst comprising: (A) preparing a catalyst support comprising a USY-type zeolite and one or more selected from silica alumina, alumina boria, and silica zirconia, and not supporting an active metal element selected from palladium and platinum, which contains a carbonaceous substance containing carbon atoms and the content of the carbonaceous substance is 0.5% by mass or less in terms of carbon atoms, (B) supporting an active metal component containing at least one active metal element selected from palladium and platinum on the catalyst support to obtain a catalyst precursor; and (C) calcining the catalyst precursor to obtain the hydroprocessing catalyst. 2. A method for producing a hydroprocessing catalyst, comprising: (A) molding a kneaded product containing a metal oxide and a molding additive having carbon atoms to obtain a molded product, (B) calcining the molded product to obtain a catalyst support comprising a USY-type zeolite and one or more selected from silica alumina, alumina boria, and silica zirconia, and without supporting an active metal element selected from palladium and platinum, which contains a carbonaceous substance containing carbon atoms and the content of the carbonaceous substance is 0.5% by mass or less in terms of carbon atoms, (C) supporting an active metal component containing at least one active metal element selected from palladium and platinum on the catalyst support to obtain a catalyst precursor; and (D) calcining the catalyst precursor to obtain the hydroprocessing catalyst.
