Abstract

The invention discloses a high-activity hydrofining catalyst and a preparation method thereof. The preparation method includes the steps: (1) taking water as solvents, and preparing slurry of silicon-phosphorus-containing alumina; (2) adding a boron-containing compound, a VIB metal compound and a VIII metal compound into the slurry, and filtering mixture to obtain filter cakes and filter liquor; (3) mixing the filter liquor, SB powder and adhesive solvents to obtain binding agents, and sequentially rolling, forming, drying and roasting the binding agents and the filter cakes to obtain the hydrofining catalyst. The silicon-phosphorus-containing alumina is a compound of SiO2, P2O5 and Al2O3. According to the preparation method, metal salt easily dissolved in water is added into the slurry, aluminum oxide, additives and the metal salt in the slurry uniformly contact with each other, the filter cakes are dried and formed, loading capacity and dispersity of metal components are improved, and synergistic effects of the additives and metal active components are furthest achieved. The catalyst is particularly applicable to removal of polycyclic aromatic hydrocarbon in naphthenic base distillate oil.

Description

technical field [0001] The invention relates to a high-activity hydrorefining catalyst and a preparation method thereof, belonging to the field of petroleum refining. Background technique [0002] Hydrofining is a general term for the catalytic upgrading of oil products in a hydrogen environment. The main reactions include hydrodeoxygenation, aromatics saturation, hydrodesulfurization, and hydrodenitrogenation. At present, most of the research on hydrorefining catalysts is the modification of the carrier and the improvement of the metal dispersion of the catalyst. [0003] There are many preparation methods of hydrorefining catalysts in the prior art, but the existing preparation methods all have unavoidable problems. Chinese patent application (CN201010222033.2) discloses a method for preparing a hydrotreating catalyst, which has the problem of metal loss. Chinese patent application (CN201010222164.0) discloses a method for preparing a hydrocracking catalyst. Although thi...
