HYDROTREATING CATALYST FOR HYDROCARBON OIL, PRODUCTION METHOD OF THE SAME, AND HYDROTREATING METHOD

PROBLEM TO BE SOLVED: To provide a hydrotreating catalyst for hydrocarbon oil, which can regenerate a catalyst having excellent desulfurization activity and high performance.SOLUTION: The hydrotreating catalyst for hydrocarbon oil is obtained by depositing, for example, molybdenum and/or tungsten in terms of oxides thereof by 15-30 parts by mass, and cobalt and/or nickel in terms of oxides thereof by 3-7 parts by mass on an inorganic oxide carrier, based on 100 parts by mass of the catalyst and has the organic acid-derived carbon content equal to or lower than 2.0 parts by mass as the elemental basis. The hydrotreating catalyst has the specific surface area of 140-350 m/g and the average pore diameter of 50-130Å when measured by a mercury penetration method. The ignition loss of the hydrotreating catalyst is 5.0% or smaller. The peak temperature of desorbed water in a temperature range until 450°C is 415°C or lower when measured by a temperature-programmed reduction method. The amount of the nitrogen monoxide to be adsorbed on the sulfided catalyst is 8.0 ml/g or larger.SELECTED DRAWING: None 【課題】脱硫活性に優れ、高性能な触媒を再生することができる炭化水素油の水素化処理触媒を提供すること。【解決手段】無機酸化物担体上に、触媒１００質量部に対して、例えばモリブデン及び／またはタングステンが酸化物換算として１５〜３０質量部担持され、コバルト及び／またはニッケルが酸化物換算として３〜７質量部担持され、有機酸由来の炭素の含有量は、元素基準として２．０質量部以下である。また触媒の比表面積が１４０〜３５０ｍ２／ｇ、水銀圧入法で測定した平均細孔径が５０〜１３０Åである。また触媒の強熱減量が５．０％以下、触媒の昇温還元法に基づいた、４５０℃までの範囲の脱離水のピーク温度が４１５℃以下、硫化処理した触媒の一酸化窒素の吸着量が８．０ｍｌ／ｇ以上である。【選択図】なし
