Hydrocracking catalyst, preparation method and use thereof, and method for hydrocracking catalytic diesel oil

Abstract:

The present disclosure provides a hydrocracking catalyst, a method for preparing the same and a use of the same, and a method for hydrocracking catalytic diesel oil. The catalyst comprises a support, an active metal component, and carbon, wherein, based on the total weight of the catalyst, the content of the support is 60 to 90 wt %, the content of the active metal component calculated in metal oxides is 15 to 40 wt %, and the content of carbon calculated in C element is 1 to 5 wt %; measured with an infrared acidimetric estimation method, the acid properties of the hydrocracking catalyst are: the total infrared acid amount is 0.4 to 0.8 mmol/g, wherein, the infrared acid amount of strong acid with desorption temperature greater than 350.degree. C. is 0.08 mmol/g or lower, and the ratio of the total infrared acid amount to the infrared acid amount of strong acid with desorption temperature greater than 350.degree. C. is 5 to 50.
