Abstract

The invention discloses a preparation method for a light-distillate oil hydrogenation treatment catalyst. The preparation method for the catalyst comprises the following steps: (1) firstly preparing acarrier of gamma-Al2O3 or titanium-containing gamma-Al2O3; (2) loading a Co metal component and a B auxiliary agent component on the carrier of the gamma-Al2O3 or the titanium-containing gamma-Al2O3,performing drying and performing roasting; and (3) impregnating the carrier obtained by the step (2) by adopting a solution containing a Ni compound, a W and / or Mo compound, performing drying and performing roasting to obtain the catalyst. The catalyst uses the gamma-Al2O3 or the titanium-containing gamma-Al2O3 as the carrier, uses Co, Ni, and W / Mo as active components, uses a B element as an auxiliary agent, can be used for hydrofining of light distillate oil such as a gasoline distillate and a kerosene distillate, and has high hydrodesulfurization activity.

Description

technical field [0001] The invention relates to a hydrogenation catalyst and a preparation method thereof, more specifically, a hydrogenation desulfurization catalyst for distillate oil, especially light distillate oil, and a preparation method thereof. Background technique [0002] No. 3 jet fuel national standard (GB 6537-2006) from the aspects of appearance, color, composition, volatility, density, fluidity, combustibility, corrosion, stability, cleanliness, conductivity, water separation index and lubricity, etc. Nearly 30 index requirements were put forward for jet fuel. Jet fuel is one of the products with the most control indicators and the strictest quality requirements among petroleum products. [0003] From a global perspective, jet fuel is mainly produced by refining straight-run components with a suitable boiling range cut from atmospheric distillation units as raw materials, and the refining process is divided into non-hydrogenation process and hydrotreating pr...
