Abstract:
1. A catalyst for hydrotreating gas oil, which comprises on an inorganic oxide support 10 to 40% by weight of at least one metal selected from metals in the Group 6 of the periodic table, 1 to 15% by weight of at least one metal selected from metals in the Group 8 of the periodic table, 1.5 to 8% by weight of phosphorus, each in terms of an oxide amount based on the catalyst, an organic acid at from 2 to 14 wt % as an amount of carbon derived from the organic acid based on the catalyst, and wherein the organic acid is contained in an amount of from 0.2 to 1.2 moles relative to 1 mole of the metal of Group 8 of the periodic table, and wherein the catalyst has a specific surface area of 150 to 300 m wherein, when the catalyst is observed on a diffuse-reflectance FT-IR after sulfidation treatment and subsequent NO adsorption, a value of I8 group/(I8 group+I6 group) is within the range of 0.7 to 1 wherein intensity of NO spectrum (1840 cm
