Embodiment 1

[0031] Weigh 50 g of MCM-22 molecular sieve. In the high-temperature treatment furnace, pass water vapor to treat, keep the treatment furnace at 550°C, and conduct hydrothermal treatment for 4 hours. The molecular sieves were treated with 500 ml of 0.5 mol / L oxalic acid solution at room temperature for 40 min. Dry at 100°C for 4 hours, and calcined at 550°C for 3 hours to obtain the modified molecular sieve M1.

Embodiment 2

[0033] Weigh 50 g of MCM-22 molecular sieve. In the high-temperature treatment furnace, water vapor was introduced to treat, and the treatment furnace was kept at 600° C., and the hydrothermal treatment was carried out for 4 hours. The molecular sieves were treated with 400 ml of 1 mol / L citric acid solution at room temperature for 20 min. Dry at 100°C for 4 hours, and bake at 550°C for 4 hours to obtain the modified molecular sieve M2.

Embodiment 3

[0035] Weigh 50 g of MCM-22 molecular sieve. In the high-temperature treatment furnace, water vapor is passed through to treat, and the treatment furnace is kept at 700° C., and the hydrothermal treatment is performed for 1 hour. The molecular sieves were treated with 500 ml of 0.01 mol / L sodium hydroxide solution at room temperature for 60 min. Dry at 120°C for 3 hours, and bake at 550°C for 4 hours to obtain the modified molecular sieve M3.

Abstract

The invention relates to a hydrogenation catalyst and a preparation method thereof. The hydrogenation catalyst comprises a reactive metal and a carrier, the reactive metal comprises a VIB-group metaland a VIII-group metal, the VIB-group metal is molybdenum and / or tungsten, the VIII-group metal is cobalt and / or nickel, the carrier comprises a solid acid component and an unformed heat-resistant oxide, the solid acid component is a mixture of an MCM-22 molecular sieve and a Beta molecular sieve, the specific surface area of the hydrogenation catalyst is 200-320m<2> / g, total pore volume is 0.30-0.50ml / g, infrared acid amount is 0.50-1.0mmol / g, the ratio of acid B to acid L is 0.2-1.0, and radial crushing strength is larger than 150N / cm. The hydrogenation catalyst is used for processes such ashydrocracking, hydro-upgrading and hydroisomerization.

Description

technical field [0001] The present invention relates to a hydrogenation catalyst and a preparation method thereof, in particular to a hydrogenation catalyst which is applied in processes such as hydrocracking, hydroreforming and hydroisomerization, and is composed of a mixture of MCM-22 molecular sieve and Beta molecular sieve as an acidic component Hydrogenation catalyst and preparation method thereof. Background technique [0002] Hydrocracking technology, as an important processing method for lightening heavy oil, upgrading inferior oil products and refining and chemical integration, has the advantages of flexible production plan, strong adaptability of raw materials, high selectivity of target products, good quality and high added value of tail oil . Hydrocracking catalyst is the core of hydrocracking technology, so the research, development and application of hydrocracking catalyst is also the main content of hydrocracking technology progress. The hydrocracking cataly...
