preparation example Construction

[0035] The preparation method of hydrocracking catalyst provided by the invention comprises the following steps:

[0036] S1 React the existing oil-soluble catalyst with the organic acid compound at 50-260°C for 1-6 hours until the reaction is complete;

[0037] S2 is then vacuum-dried at 30-80°C, cooled to room temperature to obtain an oil-soluble hydrogenation catalyst;

[0038] The existing oil-soluble catalysts are alcohol amine organic metal compounds, amino metal complexes, carbonyl organic metal compounds, and ester organic metal compounds.

[0039] Wherein, the metal in the existing oil-soluble catalyst is preferably selected from at least one of iron, nickel, cobalt, molybdenum and tungsten;

[0040] The organic acid compound is preferably ethylenediaminetetraacetic acid, oleic acid, benzoic acid, phthalic acid, 3,5-dinitrobenzoic acid, benzenesulfonic acid, p-toluenesulfonic acid, or its anhydride or Salt; the organic acid compound is further preferably phthalic ac...

Embodiment 1

[0056] Weigh 5.1g of phthalic acid to form a solution, add 55.3g of molybdenum hexyl acetate (the content of metal molybdenum is 10.2m%, denoted as A-0) into the solution, and connect the mouth of the flask with a condenser tube. The steam was condensed and refluxed, stirred with an electromagnetic stirrer during the reaction, and reacted at 160°C for 3 hours. The obtained product was fully cooled, filtered with suction, washed thoroughly, and vacuum-dried at 50°C to obtain an oil-soluble hydrogenation catalyst A.

Embodiment 2

[0058] Weigh 13.9g of benzenesulfonic acid to form a solution, add 32.8g of tungsten hexacarbonyl (metal tungsten content is 12.3m%, denoted as B-0) into the solution, connect the condenser to the mouth of the flask, and conduct Condensate and reflux, stir with an electromagnetic stirrer during the reaction, and react at 260°C for 1 hour. After the product is fully cooled, it is suction-filtered, washed with ethanol, and vacuum-dried at 30°C to obtain an oil-soluble hydrogenation catalyst B.

Abstract

The invention relates to a preparation method of a hydrocracking catalyst. The method comprises the following steps: enabling the existing oil-soluble catalyst to react with organic acid compounds for 1-6h at 50-260 DEG C until the reaction is complete; then, carrying out vacuum drying at 30-80 DEG C, and cooling to the room temperature to obtain an oil-soluble hydrogenation catalyst, wherein the existing oil-soluble catalyst is an alcohol amine-based organometallic compound, an amine-based metal complex, a carbonyl organometallic compound or an ester organometallic compound. The oil-soluble catalyst has a higher hydrocracking capacity when being used for processing inferior heavy or residue oil, can obtain a higher conversion rate, and can reduce raw coke rate to the utmost extent. The invention also provides an inferior heavy oil / residue slurry bed hydrogenation reaction method.

Description

technical field [0001] The invention relates to a preparation method of a hydrocracking catalyst, in particular to a preparation method of a slurry bed hydrocracking catalyst for inferior heavy oil and residue oil, and a method for using the catalyst in a slurry bed hydrogenation reaction of inferior heavy oil / residue oil. Background technique [0002] Crude oil is becoming increasingly heavy and inferior, the amount of imported heavy crude oil and residual oil is increasing, and the market demand for light oil products is increasing. More and more attention has been paid to it. Among them, the slurry bed residue hydrogenation technology can process lower quality residue, fuel oil and catalytic cracking oil slurry. It is an important way for refineries to reduce costs and increase efficiency, and has been valued by major international oil companies. Since the heavy oil slurry bed hydrogenation technology realizes the conversion of inferior heavy oil, the coke produced will a...
