Embodiment 1
[0050] The step of roasting at 550° C. for 4 hours in Comparative Example 2 was canceled, and the extruded strip drying condition was changed to be dried at 180° C. for 4 hours. The rest are the same to obtain catalyst C-1.
Embodiment 2
[0055] The step of roasting at 550° C. for 4 hours in Comparative Example 3 was canceled, and the extruded strip drying condition was changed to be dried at 220° C. for 5 hours. The rest are the same to obtain catalyst C-2.
Embodiment 3
[0060] The step of roasting at 550° C. for 4 hours in Comparative Example 4 was canceled, and the extruded strip drying condition was changed to be dried at 160° C. for 6 hours. The rest are the same to obtain catalyst C-3.

Abstract
The invention discloses a preparation method of a hydrogenation catalyst. According to the catalyst, a cracking molecular sieve, amorphous silica-alumina and alumina are used as carriers, and VIII and VIB metals are used as hydrogenation active components. The preparation process comprises the following steps of: mixing the cracking molecular sieve, amorphous silica-alumina and alumina for molding, drying, loading the active metals by an immersion method, drying and roasting to obtain the catalyst. In comparison with the routine immersion method, the method provided by the invention can be used to prepare the molded carriers without roasting, simplify time and energy, minimize strong interaction, help uniform distribution of the metals as well as performance of the metal activity, and avoid specific surface area loss caused by multi-step roasting. The catalyst prepared by the method is especially applicable to be used as a hydrogenation catalyst for high-yield high-quality heavy naphtha, aviation kerosene and diesel oil. By the adoption of the preparation method, activity and selectivity of the catalyst are raised.
Description
technical field [0001] The invention relates to a method for preparing a hydrocracking catalyst, in particular to a method for preparing a hydrocracking catalyst containing molecular sieves. Background technique [0002] The main features of hydrocracking technology are strong adaptability of raw materials, flexible product schemes, high selectivity of target products, good product quality and high added value, etc., and can directly produce a variety of high-quality petroleum products (such as gasoline, jet fuel, diesel oil, lubricating oil, etc.) Base oil, etc.) and high-quality chemical raw materials (such as raw materials for the production of benzene, toluene, xylene, ethylene, etc.). Therefore, as the quality of crude oil deteriorates year by year, the market demand for high-quality petroleum products and high-quality chemical raw materials continues to grow, and new environmental protection regulations have been promulgated, the importance of hydrocracking technology ...
