摘要
PROBLEM TO BE SOLVED: To obtain a hydrodesulfurization catalyst capable of removing a sulfur compound in a heavy oil fraction over a long period of time with high efficiency, to provide a manufacturing method therefor, and a method for hydrodesulfurization using the catalyst.;SOLUTION: The catalyst carries at least 8-25 mass% of one kind of metal selected from the group 6 elements of the Periodic Table on a catalyst basis in terms of the oxide, at least 1-8 mass% of one kind of metal selected from the group 8 elements of the Periodic Table, 0.5-6 mass% of phosphorus, and 1-14 mass% of carbon on the catalyst basis on an alumina carrier. Physical properties of the catalyst after baked at 500°C are as follows: the specific surface area is 180-330 m2/g, the pore volume is 0.4-0.7 ml/g, and the average pore diameter is 7-12 nm. A solution containing the above components is carried on the alumina carrier, and is dried at 200°C or lower. The raw material oil is contacted with the catalyst on the condition that 4-18 MPa of the hydrogen partial pressure, 320-410°C of the temperature, and 0.1-4.0 h-1 of the liquid space velocity are satisfied.;COPYRIGHT: (C)2004,JPO
