| description | The invention discloses a straight-run diesel oil hydrocracking catalyst and a preparation method thereof, and is characterized in that the hydrocracking catalyst is composed of a hydrogenation active center and a cracking active center, the hydrogenation active center is composed of VIB group metal and VIII group metal oxide, and the cracking active center is composed of amorphous silica-alumina and a molecular sieve. The preparation method of the catalyst comprises the following steps: 1) pre-loading the active metal; 2) forming carrier gel; 3) carrying out hydrothermal treatment on the carrier; 4) preparing an active metal solution; and 5) loading active metal components. Hydrothermal coupling modification is adopted to regulate and control the acid performance and pore structure of the cracking active component, and the active component graded loading and anchoring adsorption technology is adopted to efficiently match the hydrogenation center with the cracking center, thereby implementing the efficient co |
