Title:
炭化水素油用水素化処理触媒の製造方法及び炭化水素油の水素化処理方法
Document Type and Number:
Japanese Patent JP4545328
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a hydrotreatment catalyst for a hydrocarbon oil which can markedly reduce the sulfur content of gas oil and to provide a method for hydrotreating a hydrocarbon oil by using the catalyst. SOLUTION: This catalyst is prepared by infiltrating 10-30 wt.% (in terms of the oxide of the group 6 metal), based on the catalyst, a first solution containing a group 6 metal salt into a compound oxide support containing above 80 to 99.5 mass % alumina and 0.5 to below 20 mass % at least one member selected from zeolite, boria, silica, and zirconia, drying the support, and optionally firing the dried support and infiltrating 1-15 wt.% (in terms of the oxide of the group 8 metal), based on the catalyst, second solution containing a group 8 metal salt and an organic compound having at least one member selected from a hydroxy group, an ether bond, a carboxy group, and an amino group, and drying the support. A sulfur-containing gas oil fraction is subjected to a catalytic reaction in the presence of the catalyst under conditions including a hydrogen partial pressure of 3-8 MPa, a temperature of 300-420 deg.C and a liquid hourly space velocity of 0.3-5 hr-.
