PROBLEM TO BE SOLVED: To provide a catalyst having high hydrodesulfurization, hydrodenitrogenation, hydrodemetallation and hydrocracking activity as a heavy oil hydrotreating catalyst, and a hydrotreating method. thing. SOLUTION: In a 29 Si-NMR spectrum, -5 is obtained. The carrier having silica and alumina as main components, in which the maximum point of the main peak observed in the range of 0 to -110 ppm is in a magnetic field higher than -80 ppm and in a magnetic field lower than -100 ppm, is added to Periodic Table 6A. When at least one element selected from Group III and Group 8 is supported and calcined, the average pore diameter is 100 to 300 ° and the specific surface area is 1 30 to 300 m 2 / g, the pore volume is 0.3 ml / g or more, and the pore volume ratio of the average pore diameter ± 50 ° is the pore diameter of 60 A catalyst for hydrotreating heavy hydrocarbon oil having physical properties of 50% or more of a pore volume of 0 ° or less, and a hydrotreating method using the catalyst. |
