example 1

[0046] 800 grams of NaY molecular sieve (SiO 2 / Al 2 O 3 = 4.8, the crystallinity is defined as 100%, the product of Changling Refinery) was placed in 4000 ml of ammonium chloride (product of Beijing Chemical Factory, analytically pure) aqueous solution with a concentration of 1.0 mol, exchanged at 90 ° C for 1 hour under stirring, Filtered, washed with deionized water until no chloride ion was detected, dried at 120°C, and calcined at 550°C for 4 hours. Repeat the above process twice to obtain the Y-type molecular sieve A of the sodium content (calculated as sodium oxide) 0.35% by weight (measured by flame atomic absorption spectrometry), and the sample crystallinity measured by X-ray diffraction method is 76%, and the Y-type molecular sieve A is obtained. 200 grams were placed in 1000 milliliters of ammonium fluoride (Beijing Chemical Factory product, analytically pure) aqueous solution with a concentration of 0.2 mol, stirred at room temperature for 1 hour, filtered, drie...

[0048] Weigh 12 grams of disordered Y-type molecular sieve B in Example 1 and mix with 100 grams of SB powder (gibbsite produced by Condea, Germany) to obtain Si-2, the precursor of silica-alumina (74% by weight on a dry basis) , Si-2 was calcined at 550 °C for 4 hours, and its X-ray diffraction pattern was shown in figure 1 b, silicon oxide content and k value are shown in Table 1

example 3

[0050] Synthesize rare earth-containing five-membered ring structure zeolite according to Example 12 in CN1020269C to obtain rare earth-containing five-membered ring structure zeolite D; and synthesize partially crystallized rare earth-containing five-membered ring structure zeolite E according to the exact same conditions except that the crystallization temperature is 90°C. The rare earth-containing five-membered ring structure zeolite E has a silica content of 93.3% by weight, an alumina content of 4.5% by weight, RE 2 O 3 1.5% by weight (RE 2 O 3 Represents rare earth oxides, in which lanthanum oxide accounts for 26 wt% of the total rare earth oxides, ceria accounts for 51 wt% of the total rare earth oxides, and other rare earth oxides account for 23 wt% of the total rare earth oxides). The crystallinity of the partially crystallized ZSM-5 molecular sieve E was determined to be 6% based on the rare earth-containing five-membered ring structure zeolite D.

Description

technical field [0001] The present invention relates to a hydrocracking catalyst, and more particularly to a silica-alumina-containing hydrocracking catalyst. Background technique [0002] In recent years, the tendency of crude oil to become heavier and inferior in the world has become increasingly obvious. At the same time, the demand for middle distillates and reforming and steam cracking feedstocks has continued to increase, which promotes the use of high-quality and light heavy distillates Hydrocracking technology for chemical purposes has been developed rapidly, and hydrocracking catalyst is one of the most important and key factors. [0003] Hydrocracking catalyst is a dual-function catalyst, it has both hydrogenation activity and cracking activity, that is, it contains both hydrogenation active components and acidic components. The hydrogenation active components are generally selected from VIB and VIII in the periodic table of elements. Gr...
