[0041] Example 1
[0042] This embodiment provides a phosphorus-containing HY molecular sieve (P 2 O 5 The content is 3wt%), which includes the following steps:
[0043] Add 4.24g of NaOH solid (NaOH≥96wt%), 2.09g of NaAlO 2 Solid (Al 2 O 3 ≥45wt%) dissolved to 19.95g of H 2 O, add 22.72g of water glass solution (SiO 2 , 28m%, modulus: 3.3), stand aging at room temperature for 24h to prepare a directing agent;
[0044] Add 7.2g of phosphoric acid to 130.97g of H 2 After stirring evenly in O, mix with 0.15g NaOH and 13.09g NaAlO 2 After mixing, place in a 500mL plastic beaker, then add 142.43g of water glass solution and stir vigorously to prepare mother liquor;
[0045] The directing agent was added dropwise to the mother liquor, stirred vigorously for 20 minutes, then transferred to the crystallization kettle, aged for 24 hours at room temperature, and crystallized at 100°C for 22 hours; after the material obtained after crystallization was washed until the pH value of the filtrate wa...

[0048] This embodiment provides a phosphorus-containing HY molecular sieve (P 2 O 5 The content is 2wt%), which includes the following steps:
[0049] Add 4.24g of NaOH solid (NaOH≥96wt%), 2.09g of NaAlO 2 Solid (Al 2 O 3 ≥45wt%) dissolved to 19.95g of H 2 O, then add 22.72g of water glass solution (SiO 2 , 28m%, modulus: 3.3), stand aging at room temperature for 24h to prepare a directing agent;
[0050] Add 5.1g phosphoric acid to 130.97g H 2 After stirring evenly in O, mix with 0.15g NaOH, 13.09g NaAlO 2 After mixing, place in a 500mL plastic beaker, then add 142.43g of water glass solution and stir vigorously to prepare mother liquor;
[0051] The directing agent was added dropwise to the mother liquor, stirred vigorously for 20 minutes, then transferred to the crystallization kettle, aged for 24 hours at room temperature, and crystallized at 100°C for 22 hours; after washing the material obtained after crystallization until the pH of the filtrate is less than 9,...
Example Embodiment
[0053] Example 3
[0054] This embodiment provides a method for preparing a heavy oil hydrogenation catalyst, which mainly adopts PY / TiO modified with nickel 2 -Al 2 O 3 (Organic titanium source + organic aluminum source) The method for supporting the active component (metal Ni-W) on the composite carrier, the method specifically includes the following steps:
[0055] Nickel modified PY / TiO 2 -Al 2 O 3 Preparation of composite carrier: Weigh 34.0g of tetrabutyl titanate and 20.8g of aluminum isopropoxide and dissolve in 150mL of ethanol to obtain solution A; add 1.64g of nickel nitrate hexahydrate crystals to solution A, and stir to dissolve; 19mL of water, 41.2mL of acetic acid and 40mL of absolute ethanol were mixed to obtain solution B; under vigorous stirring, solution B was dropped into solution A for reaction; after dripping and reacting for 20 minutes, 3g prepared in Example 1 was added 3PY molecular sieve, reacted for 10 minutes to obtain a sol, and the sol is aged for 24h-...
