preparation example Construction

[0033] The invention provides a kind of preparation method of Y / SSZ-13 / rare earth / ASA composite material, comprises the steps:

[0034] Step 1, mixing Y molecular sieve, SSZ-13 molecular sieve, aluminum source, basic compound and water, heating and stirring;

[0035] Step 2, adding silicon source and rare earth precursor to the mixture in step 1, heating and stirring to obtain Y / SSZ-13 / rare earth / ASA composite material.

[0036] The invention adopts Y-type molecular sieve, SSZ-13 molecular sieve, rare earth and amorphous silicon-aluminum as the cracking center, and the composite material prepared by step-by-step precipitation method has micropore-mesoporous structure. Among them, although SSZ-13 molecular sieve is a small-pore molecular sieve, it has a significant isomerization function in the cracking reaction of heavy oil molecules, especially in the reaction of diesel hydrocracking to produce jet fuel. The combination of SSZ-13 molecular sieve and Y-type molecular sieve, r...

Embodiment 1

[0052] (1) According to the amount that the total weight of molecular sieve accounts for 50wt% of the weight of the composite material, weigh 19g of Y-type molecular sieve with a silicon-aluminum ratio of 7.5 and 1g of SSZ-13 with a silicon-aluminum ratio of 20 and add them to the reactor.

[0053] (2) The solid aluminum sulfate is prepared into 500mL concentration of 20g Al 2 o 3The aluminum sulfate solution (A) of / L is added the dilute ammonia solution (B) of 10wt% by adding an amount of deionized water to the strong ammonia water, gets the concentrated water glass solution and adds an amount of deionized water and is diluted into the water glass solution of 72mL 14wt% ( C). Take 2g cerium nitrate (Ce(NO 3 ) 3 ·6H 2 O), join in 10mL water, obtain CeO 2 Solution (D) with a content of 6.61%.

[0054] (3) Add 100mL deionized water to the reaction kettle and heat it to 75°C, add (A) and (B) to make the mixed slurry gel for 60min under the condition of pH 8.0, after the fe...

Embodiment 2

[0062] (1) According to the addition of 50 wt% of the total weight of the molecular sieve to the weight of the composite material, 14g of Y-type molecular sieve with a silicon-aluminum ratio of 10 and 6g of SSZ-13 molecular sieve with a silicon-aluminum ratio of 50 were weighed and added to the reactor.

[0063] (2) The solid aluminum sulfate is prepared into 500mL concentration of 20g Al 2 o 3 The aluminum sulfate solution (A) of / L is added the dilute ammonia solution (B) of 10wt% by adding an amount of deionized water to the strong ammonia water, gets the concentrated water glass solution and adds an amount of deionized water and is diluted into the water glass solution of 72mL 14wt% ( C). Take 2g of lanthanum nitrate (La(NO 3 ) 3 ·6H 2 O), was added to 10mL water to obtain La 2 o 3 Solution (D) with a content of 3.76%.

[0064] (3) Add 100mL deionized water to the reaction kettle and heat it to 75°C, add (A) and (B) to make the mixed slurry pH 8.5 and carry out gela...

The Y / SSZ-13 / rare earth / ASA composite material is prepared by the following steps: step 1, mixing a Y molecular sieve, an SSZ-13 molecular sieve, an aluminum source, an alkaline compound and water, heating and stirring; and 2, adding a silicon source and a rare earth precursor into the mixture in the step 1, heating and stirring to obtain the Y / SSZ-13 / rare earth / ASA composite material. The catalyst prepared from the composite material provided by the invention is suitable for a straight-run diesel oil hydrocracking high-yield aviation kerosene process.

Description

technical field [0001] The invention belongs to the field of oil refining catalysts, and in particular relates to a Y / SSZ-13 / rare earth / ASA composite material and a preparation method thereof, a hydrocracking catalyst carrier and a preparation method thereof, a hydrocracking catalyst and a preparation method thereof. Background technique [0002] With the continuous expansion of the international air transport industry, the global demand for jet fuel is increasing year by year, with an annual growth rate of about 5.0%, far higher than the annual growth rate of gasoline and diesel of 1.0% to 1.5%, which has greatly driven the global Demand for high-quality aviation fuel products in the oil market. In 2019, China's domestic air transport industry showed a good momentum of development. Against the backdrop of an overall slowdown in demand growth in the refined oil market, the aviation fuel market still maintains a booming supply and demand and a high-speed growth trend. Accord...
