Title:
固体酸触媒、その製造方法およびそれを使用する軽質炭化水素油の水素化脱硫異性化方法
Document Type and Number:
Japanese Patent JP4182663
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a high activity molded catalyst having high compressive strength, free of breaking when packed into a reactor vessel and retaining its original solid acidity as a solid acid catalyst which simultaneously desulfurizes and isomerizes light hydrocarbon oil containing organic sulfur compounds. SOLUTION: (A) A sulfuric acid radical-containing material is added to zirconium hydroxide to sulfate the zirconium hydroxide, (B1 ) pseudo-boehmite is added as a binder to the sulfated zirconium hydroxide and kneaded with an aqueous solution containing a group VIII metal or (B2 ) a group VIII metal is carried on the sulfated zirconium hydroxide and kneaded with an aqueous solution containing a binder, (C) the kneaded material is molded in a catalyst shape and (D) the resulting molding is fired at 550-800 deg.C to produce the objective catalyst. In hydrodesulfurization and isomerization, light hydrocarbon oil having <=700 mass ppm sulfur content and hydrogen are brought into contact with the catalyst under the reaction conditions of 160-240 deg.C, 1.0-4.5 MPa pressure, 1.0-10 h<-1> LHSV and a hydrogen to oil ratio of 100-1,000 NL/L.
