Embodiment 1

[0026] 1200 grams of clover-shaped alumina strips (marked as S0 carrier, roasted at 600 ° C for 4 hours) with a circumscribed circle diameter of 1.4 mm from Changling Catalyst Branch were immersed in 1320 milliliters of aqueous solution containing 450 grams of ammonium citrate for 8 hours , and then dried at 120° C. for 8 hours, and then heated to 600° C. for 2 hours under an argon atmosphere to activate the carbon-containing support S1. The carbon content, specific surface area, and pore volume of support S1 are listed in Table 1, respectively.

[0027] Carbon content is determined by RIPP-90 ("Petrochemical Analysis Method (RIPP Test Method)", Science Press, 1990, 418-419), and the specific surface area and pore volume of the carrier are determined by BET low-temperature nitrogen adsorption method (the same below). .

Embodiment 2

[0029]Take 1200 grams of SO carrier, impregnate with 1320 ml of aqueous solution containing 352 grams of ammonium citrate for 4 hours, then dry at 120° C. for 7 hours, then heat up to 550° C. and activate for 4 hours under an argon atmosphere to obtain carbon-containing carrier S2. The carbon content, specific surface area, and pore volume of support S2 are listed in Table 1, respectively.

Embodiment 3

[0031] Take 1200 grams of SO carrier, impregnate with 1320 milliliters of aqueous solution containing 213 grams of ammonium citrate for 6 hours, then dry at 120 ° C for 4 hours, and then heat up to 610 ° C under an argon atmosphere for activation for 2 hours to obtain carbon-containing carrier S3. The carbon content, specific surface area, and pore volume of support S3 are listed in Table 1, respectively.

Abstract

The invention relates to a distillate oil hydrorefining catalyst which contains carbon-containing molded heat-resisting oxide carrier, molybdenum and/or tungsten metal component that are/is loaded on the carrier and selected from VIB cluster and nickel and/or cobalt metal component selected from VIII cluster; the method is based on the oxide and takes catalyst as reference; and the content of molybdenum and/or tungsten is 5-40wt%, and the content of nickel and/or cobalt is 1-8wt%. The carbon-containing carrier is prepared by the method comprising the steps of: (1) adopting water solution containing one or more in organic carboxylic acid and organic carboxylic acid salt for dipping the molded heat-resisting oxide carrier; (2) drying the product obtained in the step (1), and activating under the condition that inert gas exists; and in the steps (1) and (2), due to the dosage of the components and the operation condition, the weight ratio between carbon and the heat-resisting oxide in the carrier is 0.1:99.9-10:90. Compared with the existing catalyst, the catalyst has high hydrodesulphurization activity.

Description

technical field [0001] The invention relates to a distillate oil hydrogenation catalyst. Background technique [0002] Increasing awareness of environmental protection and stricter environmental regulations force the oil refining industry to pay more attention to the development of clean fuel production technology. How to economically and reasonably produce ultra-low sulfur oil products has become one of the key issues that the oil refining industry needs to solve at present and in a certain period of time in the future. one. The development of new hydrogenation catalysts with higher activity and selectivity is one of the most economical ways to produce clean oils. [0003] As one of the important components of hydrogenation catalysts, the surface physicochemical properties of the support have an important impact on the catalytic performance of the catalyst. Steven L. Butterworth et al. used anthracene and propylene to cover carbon on γ-alumina, and found that the hydrodes...
