Abstract

The invention relates to a method for preparing a high-performance hydrocracking catalyst, which comprises the following steps: preparing amorphous aluminium-silicon into a paste material of which the pH value is between 3.0 and 5.5, evenly mixing Y zeolite solid powder of modified rare earth with the paste material of the amorphous aluminium-silicon, and then drying and dehydrating the mixture to prepare a moldable paste so as to prepare a catalyst carrier through molding, drying, and calcining, and finally obtaining the final hydrocracking catalyst by loading hydrogenation metal components through an impregnation method. The hydrocracking catalyst prepared by the method has the advantages of high activity and middle oil selectivity, and strong nitrogen resisting performance and water resistance, thus the hydrocracking catalyst can be used in the process of an unrefined single-stage hydrocracking, which not only can be used for processing heavy oil fraction of oil, but also can be used for processing heavy raw materials of other sources, such as the heavy distillate of coal liquefaction oil.

Description

technical field

[0001] The invention relates to a preparation method of a high-performance hydrocracking catalyst, in particular to a preparation method of a hydrocracking catalyst containing modified Y-type molecular sieves with strong impurity resistance capability. Background technique

[0002] At present, the world's oil resources are insufficient, the crude oil has become heavier and worse, and the impurity content has increased, while the demand for clean and high-quality light fuels is increasing, especially the demand for clean middle distillates. In addition, with the rising price of natural oil, various other sources of energy are increasingly entering the processing ranks, such as direct coal liquefied oil, indirect coal liquefied oil, coal tar, shale oil, animal and vegetable oils, etc. Feedstocks from these sources share a common feature of higher oxygen content compared to natural oil, which presents new problems for further processing.
