Embodiment 1

[0021] Take 20 grams of industrial catalytic cracking catalyst, marked as M, and add it into 50 ml of water and stir to make a slurry. Then, under the condition of 80°C water bath, 50ml of 0.65mol / L boric acid solution was added to obtain an acidified catalytic cracking catalyst suspension, and the reaction time was kept for 0.5h. 1.0 mol / L dilute nitric acid was added to the obtained mixture to adjust the pH to 3.0, and the reaction was continued for 24 hours under stirring in a water bath at 80°C. Finally, the reacted sample was suction-filtered, washed, dried at 110°C for 8 hours, and then calcined at 500°C for 4 hours to obtain a product marked as sample A.

Embodiment 2

[0023] Take 20 grams of Y-type molecular sieves, marked as N, add 50ml of water and stir for beating. Then, under the condition of 80°C water bath, 50ml of 0.65mol / L boric acid solution was added to obtain acidified pseudo-boehmite suspension, and the reaction time was 0.5h. Add 1.0 mol / L dilute nitric acid to the resulting mixture to adjust the pH to 3.0, and continue to react continuously for 24 h under the condition of stirring in a water bath at 80°C. Finally, the reacted sample was suction-filtered, washed, dried at 110° C. for 8 hours, and then calcined at 500° C. for 4 hours to obtain modified molecular sieve sample B.

Embodiment 3

[0025] Take 20 grams of Y-type molecular sieves, mark them as N, soak them in an aqueous solution containing 0.4 g of boric acid, and let them stand at room temperature for 12 hours. Then the obtained sample was dried at 80° C. for 8 h, and calcined at 500° C. for 4 h to obtain sample C.

Abstract

The invention relates to a preparation method for a catalytic cracking catalyst for petrifaction, and particularly relates to a low-L-acid and high-B-acid catalytic cracking catalyst and a preparation method thereof. The preparation method comprises the following steps: adding a catalytic cracking catalyst into deionized water, adding boric acid solution at the temperature of 20-90 DEG C, adding inorganic acid, carrying out suction filtration and washing on the product subjected to reaction, and drying and roasting the obtained filter cake to obtain the low-L-acid and high-B-acid catalytic cracking catalyst. According to the preparation method for the low-L-acid and high-B-acid catalytic cracking catalyst provided by the invention, a boron element is introduced into the catalytic cracking catalyst, so that the surface L-acid content of the catalytic cracking catalyst is reduced, and the B-acid content thereof is increased; the low-L-acid and high-B-acid catalytic cracking catalyst is capable of increasing a raw material conversion rate, effectively increasing the yields of catalytic cracking gasoline and diesel oil, and reducing the yield of light hydrocarbons when being used for catalytic cracking micro-reaction.

Description

technical field [0001] The invention relates to a method for preparing a catalytic cracking catalyst for petrochemicals, in particular to a low-L acid and high-B acid catalytic cracking catalyst and a preparation method thereof. [0002] technical background [0003] Catalytic cracking is one of the important methods for the secondary processing of heavy oil and the production of clean oil products such as gasoline and diesel. As a catalytic cracking catalyst that dominates the catalytic reaction of petroleum hydrocarbon molecules, it is mainly composed of active components, namely molecular sieves and substrates, and sometimes with the aid of The role of the binder. Industrial applications require catalytic cracking catalysts to have good physical and chemical properties, such as: large specific surface area, high mechanical strength, strong thermal stability, and acidic surface. The catalytic cracking catalyst also has acid (B acid) and Lewis acid (L acid). Among them, ...
