Problems solved by technology

The hydrocracking catalyst is prepared by using the hydrocracking catalyst intermediate, which does not need to go through the generation reaction of hydrogen sulfide and the sulfidation reaction of hydrogen sulfide and active metal during roasting and vulcanization, and does not generate additional heat, which is a good solution to the external pre-sulfurization The airtightness and exothermic problems of the catalyst avoid the problem of excessive temperature rise during the catalyst vulcanization process

Embodiment 1

[0060] Example 1 Preparation of Hydrocracking Catalyst A

[0061] Weigh 26.5 g of ammonium molybdate, 25 g of nickel nitrate, and 50 mL of ammonia water, and mix them with deionized water to 100 mL to obtain solution I. Dissolve 30 g of 2,4,6-trimercapto-s-triazine triammonium salt in 50 mL of water to obtain solution II. Weigh 12.7 grams of Y molecular sieve (SiO 2 / Al 2 o 3 The molar ratio is 16, and the specific surface area is 613m 2 / g, total pore volume 0.48mL / g), 35.5 grams of amorphous silicon aluminum (SiO 2 Content 50wt%, pore volume 0.85ml / g, specific surface area 370m 2 / g, dry basis 70wt%) and 61.5 grams of macroporous alumina (pore volume 1.0ml / g, specific surface area 400m 2 / g, dry basis 70wt%), then put into 2L water, after vigorously stirring for 20min, add solutions I and II side by side, then stir for another 30min, wash, and filter with suction. The filter cake obtained by suction filtration was heat-treated at a low temperature of 80° C. for 3 hour...

[0062] Example 2 Preparation of Hydrocracking Catalyst B

[0063] Take 21.8g of molybdenum oxide, 10.7g of basic nickel carbonate, 2mL of phosphoric acid, and 60mL of deionized water, mix them uniformly and boil for 1 hour to obtain solution I. Weigh 42 g of 2,4-dimercapto-s-triazine diammonium salt and dissolve it in 100 mL of acetone solution to obtain solution II. Weigh 12.7 grams of Y sieve (SiO 2 / Al 2 o 3 The molar ratio is 16, and the specific surface area is 613m 2 / g, total pore volume 0.48mL / g), 35.5 grams of amorphous silicon aluminum (SiO 2 Content 50wt%, pore volume 0.85ml / g, specific surface area 370m 2 / g, dry basis 70wt%) and 61.5 grams of macroporous alumina (pore volume 1.0ml / g, specific surface area 400m 2 / g, dry basis 70wt%), then put it into 2L of water, after vigorously stirring for 20min, drop solution I into the slurry and stir for 10min, then drop solution II into the slurry, stir vigorously during the dropping process, and then stir for 30min A...

Embodiment 3

[0064] Example 3 Preparation of Hydrocracking Catalyst C

[0065] Prepare the solution I of Example 1 with the same mass and concentration. Dissolve 75 g of 2,4,6-trimercapto-s-triazine monoammonium salt in 50 mL of water to obtain solution II. Weigh 9.7 grams of Y molecular sieve (SiO 2 / Al 2 o 3 The molar ratio is 16, and the specific surface area is 613m 2 / g, total pore volume 0.48mL / g), 12.2 grams of β molecular sieve (SiO 2 / Al 2 o 3 The molar ratio is 82, and the specific surface area is 546m 2 / g, total pore volume 0.46mL / g) and 100 grams of macroporous alumina (pore volume 1.0ml / g, specific surface area 400m 2 / g, dry basis 70wt%), then put into 2L water, after vigorously stirring for 20min, add solutions I and II side by side, then stir for another 30min, wash, and filter with suction. Other steps were the same as in Example 1 to obtain hydrocracking catalyst C, whose main physical properties are shown in Table 1.

Abstract

The present invention discloses a hydrocracking catalyst intermediate, a hydrocracking catalyst, and preparation methods of the hydrocracking catalyst intermediate and the hydrocracking catalyst. According to the present invention, the hydrocracking catalyst intermediate comprises a hydrogenation activity metal component, a carrier containing an acid cracking component, and a specific organic compound, and does not require a hydrogen sulfide generation reaction and a vulcanization reaction between hydrogen sulfide and an active metal during calcination vulcanization, such that the problem that the temperature increase is too rapid during the traditional catalyst vulcanization process can be avoided; and the hydrocracking catalyst has advantages of complete vulcanization, good metal dispersibility, and good hydrogenation property.

Description

technical field [0001] The invention relates to a preparation method of a hydrogenation catalyst, in particular to a hydrocracking catalyst intermediate, a hydrocracking catalyst and a preparation method thereof. Background technique [0002] At present, the shortage of petroleum resources in the world, the quality of crude oil is deteriorating year by year, the demand for middle distillate oil is increasing, the upgrading of petrochemical products and the stricter environmental regulations have greatly promoted the transformation of heavy oil into lighter products, and constituted an accelerated development of hydrogenation. The power of technology. The main features of hydrocracking technology are strong adaptability of raw materials, high selectivity of product plans and target products, good product quality and high added value, and can directly produce a variety of high-quality petroleum products (such as gasoline, jet fuel, diesel oil, lubricating oil base Oil, etc.) ...
