Embodiment 1

[0056] 50.0g of ferrous sulfate heptahydrate and 0.20g of EDTA were dissolved in 400g of deionized water, stirred evenly, another 25.0g of ammonia water was dripped into the above solution while stirring, air was introduced and continued to stir for 20min, then suction filtration and washing were carried out to obtain The filter cake was dried at 105°C for 2 hours, crushed and sieved to obtain a powdery iron-containing compound, denoted as Fe~1. The prepared Fe~1 and FCC-1 were mixed at a ratio of 1:5 to obtain residue hydrogenation catalyst A1.

Embodiment 2

[0058] Weigh 35g of ferrous sulfate heptahydrate and 0.12g of ammonium dihydrogen phosphate into a beaker, add 200g of deionized water and stir continuously to dissolve, weigh 50.0g of FCC~1 agent and add to the above solution, add 17g of ammonia water drop by drop while stirring After the dropwise addition, the air was introduced and continued to stir for 20 minutes, then suction filtered and washed to obtain a filter cake which was dried at 105° C. for 3 hours, pulverized and sieved to obtain the residual oil hydrogenation catalyst A2. The content of hydrated iron oxide in A2 is 18.2wt%, and the content of spent catalytic cracking catalyst is 81.8wt%.

Embodiment 3

[0060] Weigh 9.4g of ferrous acetate and 0.05g of EDTA into a beaker, add 100g of deionized water and stir continuously to dissolve, weigh 50.0g of FCC ~ 1 dosage and add it to the ferrous sulfate solution, add 7.0g of ammonia water drop by drop while stirring, drop After the addition, air was introduced and stirring was continued for 30 minutes, then suction filtered and washed to obtain a filter cake which was dried at 105°C for 2 hours, pulverized and sieved to obtain a residual oil hydrogenation catalyst which was designated as A3. The content of hydrated iron oxide in A3 is 8.5wt%, and the content of spent catalytic cracking catalyst is 91.5wt%.

Abstract

A residual oil hydrocracking catalyst is benchmarked against the total quantity of catalysts, and comprises 2 wt%-20 wt% of a ferric oxide hydrate, 27 wt%-55 wt% of a molecular sieve, and 30 wt%-70 wt% of a heat-proof inorganic oxide carrier. Preferably, the catalyst comprises the ferric oxide hydrate and a catalytic cracking spent catalyst. The catalyst can be prepared in a coprecipitation method, and according to Fe, the adding amount of the catalyst is 0.1 wt%-1.0 wt% of the amount of the residual oil raw material. The catalyst provided by the invention is suitable for hydrocracking asphaltene super heavy oil with high metallic content and inferior residual oil, has the advantages of simple preparation method, low cost, and high light oil yield, and does not contain noble metals.

Description

technical field [0001] The present invention relates to a residual oil hydrocracking catalyst for producing light fuel, a preparation method of the catalyst, and a residual oil hydrocracking method using the catalyst. Background technique [0002] The increasingly heavy and inferior quality of the world's petroleum resources and the contradiction between the rapid economic growth and the increasing demand for petroleum products have caused refineries to pay more and more attention to heavy oil lightening technology. Among them, slurry bed residue hydrocracking The process has strong competitiveness and good development prospects because it can handle low-quality raw materials with high residual carbon and high metal content. Catalyst is one of the core technologies of residual oil hydrocracking process. It is very important for reducing the severity of the reaction, improving the reaction efficiency, improving the oil yield, reducing the coke yield, thereby reducing the proc...
