摘要： PROBLEM TO BE SOLVED: To highly hydrogenate a heavy oil and remarkably decrease the sulfur content, etc., of a crude heavy oil while minimizing the loss of fraction caused by excessive decomposition by carrying out hydrogenative isomerizing desulfurization treatment of a heavy oil in the presence of a hydrogenative isomerizing desulfurization catalyst. SOLUTION: A heavy oil such as asphalt oil is hydrogenated by the hydrogenative isomerizing desulfurization treatment of the oil in the presence of a hydrogenative isomerizing desulfurization catalyst comprising at least one kind of metal selected from the group 6 and the groups 8-10 elements of the periodic table (e.g. Ni/Mo) and phosphorus supported on a carrier preferably containing an acid-treated zeolite preferably at a reaction temperature of 360-420 deg.C under partial hydrogen pressure of 100-180 kg/cm2G. The above catalyst preferably contains 5-90 wt.% acid-treated zeolite in terms of carrier, 2-40 wt.% supported metal in the catalyst in terms of oxide based on the catalyst and 1-10 wt.% phosphorus in terms of oxide based on the catalyst.

摘要： PROBLEM TO BE SOLVED: To effectively use even the pore surfaces in a catalyst and to efficiently remove metal impurities such as vanadium and nickel from heavy oil by preparing a hydrogenation demetallizing catalyst for heavy oil from silica having a controlled range of average pore diameter and containing no group 6 metals in the periodical table. SOLUTION: This hydrogenation demetallizing catalyst for heavy oil is prepared from silica having 150 to 1,000 Å average pore diameter and containing no group 6 metals in the periodical table and containing at most 1 wt.% of other metals calculated as oxides. In the production of the silica-based catalyst, first a silica sol is dehydrated at a high temp. or dehydrated and condensed with addition of an acid or alkali to obtain gel. The gel is washed with water, formed and dried and calcined at 80 to 200 deg.C drying temp. for 0.5 to 10 hours of drying time and at 300 to 600 deg.C calcining temp. and 0.5 to 8 hours of calcining time to obtain a silica catalyst. During forming, a binder may be added, and in this case, the silica content is preferably controlled to >=50 wt.%.
