Provided is a hydrotreating catalyst for a heavy hydrocarbon oil, the catalyst including an inorganic oxide carrier including alumina as a main component and a metal component supported on the inorganic oxide carrier, the catalyst having a specific surface area within a predetermined range, a reduction peak temperature that is lower than 450&#xb0; C. in temperature-programmed reduction measurement of the catalyst and that is higher than or equal to a predetermined temperature, and an amount of nitrogen monoxide adsorbed on the sulfided catalyst within a predetermined range.

Hydrotreating catalyst for heavy hydrocarbon oil, method for producing the same, and method for hydrotreating heavy hydrocarbon oil

Provided herein is a hydrotreating catalyst for hydrocarbon oil having high desulfurization activity, and high abrasion strength and high compressive strength. A process for producing the hydrotreating catalyst is also provided. The hydrotreating catalyst uses an alumina-phosphorus support. The support contains 0.5 to 2.0 mass % of phosphorus in terms of an oxide. The support loads a metal in Group 6A of the periodic table, and a metal in Group 8 of the periodic table. The hydrotreating catalyst has a specific surface area of 150 m/g or more. The hydrotreating catalyst has a total pore volume of 0.40 to 0.75 ml/g as measured by a mercury intrusion method. The hydrotreating catalyst has two maximal peaks in a pore diameter range of 6 nm to 13 nm in a log differential pore volume distribution measured by a mercury intrusion method. The hydrotreating catalyst has an abrasion strength of 0.5% or less. The hydrotreating catalyst has a compressive strength of 15 N/mm or more. The support is produced from, for example, a hydrate obtained by adding phosphorus to an alumina hydrate obtained by using two mixtures of an acidic aqueous aluminum salt solution and a basic aqueous aluminum salt solution.

Hydrotreating catalyst for hydrocarbon oil, process for producing same, and hydrotreating method

A hydrotreating catalyst includes a hydrogenation active metal supported on a alumina-phosphorus support and satisfies: a specific surface area being 100 m/g or more; a total pore volume measured by mercury intrusion being in a range 0.80-1.50 ml/g; a maximum value of pore distribution being present in a pore diameter range 10-30 nm; a ratio of a pore volume of pores with a pore diameter within a range of &#xb1;2 nm of a pore diameter at the maximum value to a pore volume of pores with a pore diameter in a range 5-100 nm being 0.40 or less; a pressure capacity being 10 N/mm or more; 0.4-10.0 mass % of phosphorus being contained in the catalyst in terms of POconcentration based on a total amount of the catalyst; and a hydrogenation active metal being at least one metal selected from metals of VIA and VIII groups of the periodic table.
