Abstract

The invention discloses a hydrogenation catalyst, which takes gamma-Al2O3 or siliceous gamma-Al2O3 as a carrier and Ni, Co, W and / or Mo as active components and also contains B auxiliaries. The invention also relates to a preparation method of the hydrogenation catalyst, comprising the following steps: (1) uniformly mixing pseudo-boehmite powder with a certain proportion of sesbania powder, then adding a peptizator and deionized water for kneading, and then carrying out extruding, drying and calcinating to obtain the gamma-Al2O3 or siliceous gamma-Al2O3 carrier; (2) loading the gamma-Al2O3 or siliceous gamma-Al2O3 carrier with impregnation liquid prepared from an Ni containing compound, a B containing compound and other auxiliaries by an impregnation method, and then carrying out drying and calcinating to obtain the semi-finished product of the catalyst; and (3) loading the semi-finished product of the catalyst with impregnation liquid prepared from a Co containing compound, a W and / or Mo containing compound and other auxiliaries by the impregnation method, and then carrying out drying and calcinating to obtain the finished product of the catalyst.

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...
