Embodiment 1

[0032] Mix the large-pore pseudo-boehmite (Shandong Zibo Qilin Chemical Industry Co., Ltd.) with a dry basis of 80 g and the small-pore pseudo-boehmite (Shandong Zibo Qilin Chemical Industry Co., Ltd.) with a dry basis of 20 g and add 1 L of water to make a slurry. After 30 minutes, respectively Add zirconium nitrate and magnesium nitrate (including Zr 5g, Mg 1g) to the slurry, raise the temperature to 60°C during the stirring process, keep the temperature for 1 hour, add ammonia water to the slurry to adjust the pH value to 10, and then stir for 1 hour before suction filtration After washing and drying overnight, add 5 g of kale powder to the dry powder and mix evenly, then add a solution (containing 1 g of P) consisting of phosphoric acid, nitric acid and 60 g of deionized water, and knead evenly to make a dough suitable for extrusion. It is extruded through a die, and the shape is a slender cylinder (cross-sectional diameter 1.5mm), dried at 120°C and calcined at 600°C for 4...

Embodiment 2

[0034] Mix silicon oxide (Zibo, Shandong) with a dry basis of 80 g and small-pore pseudoboehmite (Zibo Qilin Chemical Industry, Zibo, Shandong) with a dry basis of 80 g and add 1 L of water to make a slurry. After 30 minutes, add zirconium nitrate and nitric acid to the slurry Magnesium (including Zr 5g, Mg 1g), the temperature was raised to 60°C during the stirring process, and after constant temperature for 1 hour, ammonia water was added to the slurry to adjust the pH value to 10. After adding 5g of scallop powder and mixing evenly, add a solution (containing P 1g) consisting of phosphoric acid, nitric acid and 60g of deionized water, and knead evenly to make a dough suitable for extrusion. It is extruded through a die, and the shape is a slender cylinder (cross-sectional diameter 1.5mm), dried at 120°C and calcined at 600°C for 4 hours, and then cut into carrier particles (1.5×4.0mm) of the same size. Final carrier material 2.

Abstract

The invention relates to a distillate oil hydrofining catalyst carrier and a preparation method thereof and mainly solves the problems that traditional hydrofining catalysts have non-centralized pore diameter distribution and poorer coking resistance and stability. The technical scheme is as follows: hydrofining catalyst carrier is prepared from, in percentage by weight, 68%-69.5% of at least one of aluminum oxide, silicon oxide and amorphous silicon-aluminum, 10%-20% of small-pore aluminum oxide, 0.5%-2% of P, 1%-8% of Zr and 0.5%-2% of Mg, so that the problems are better solved. According to the carrier preparation method, metal is added in the carrier preparation process, and the carrier has the characteristics of high strength, medium acidity and centralized pore diameter distribution and can be applied to the distillation oil refining field.

Description

technical field [0001] The invention relates to a distillate oil hydrogenation catalyst carrier and a preparation method thereof. Background technique [0002] With the increasing demand for gasoline and diesel in transportation fuels and the environmental pollution caused by engine exhaust, countries all over the world have begun to strictly limit the quality of fuel products, especially the sulfur content. In order to meet the needs of my country's oil refining industry to produce clean fuels and process sulfur-containing crude oil, oil refineries will pay more attention to and apply more hydrorefining technology. Hydrofining technology can effectively hydrogenolyze sulfur, nitrogen, oxygen and other heteroelement compounds contained in oil to meet the needs of downstream processing. While having good development opportunities, hydrorefining technology will also face some new changes. At the present stage, the crude oil extracted by my country itself is relatively heavy ...
