Abstract

A method for preparing a distillate oil hydrotreating catalyst, comprising the following processes: (1) mixing pseudoboehmite powder and Tianqing powder evenly, adding peptizer, deionized water, etc. and kneading, then extruding, drying, and roasting, Obtain gamma-Al2O3 or silicon-containing gamma-Al2O3 carrier; (2) use impregnation method to load the impregnating solution prepared by containing Mo compound and B compound, then dry and roast to obtain the catalyst semi-finished product; (3) step (2) ) The catalyst semi-finished product described in the impregnation method is used to load the impregnation solution prepared by the compound containing W, the compound containing Ni and/or Co, and then dry and roast to obtain the finished catalyst; the catalyst can be used for reforming raw materials, gasoline fractions and kerosene Distillate and other light distillate oils are hydrotreated and have high hydrodesulfurization activity.

Description

technical field [0001] The invention relates to a method for preparing a hydrorefining catalyst, more specifically, a method for preparing a hydrodesulfurization catalyst for distillate oil, especially light distillate oil. 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 process . [0004] Due to the ...
