Embodiment 1

[0018] Weigh 50g of silica sol, 950g of aluminum hydroxide dry glue, add 42g of acetic acid, 25g of citric acid, 25g of succulent powder and 700ml of deionized water, add 25ml of ammonia water, knead evenly, and then extrude into strips. The carrier Z1 was prepared by drying at 110°C for 4h and calcining at 550°C for 3h.

Embodiment 2

[0020] Weigh 75g of silica sol, 925g of aluminum hydroxide dry glue, add 42g of acetic acid, 25g of citric acid, 25g of succulent powder and 700ml of deionized water, add 25ml of ammonia water, knead evenly, and then extrude into strips. The carrier Z2 was obtained by drying at 110°C for 4h and calcining at 550°C for 3h.

Embodiment 3

[0022] Weigh 100g of silica sol, 900g of aluminum hydroxide dry glue, add 42g of acetic acid, 25g of citric acid, 25g of succulent powder and 700ml of deionized water, add 25ml of ammonia, knead evenly, and then extrude into strips. The carrier Z3 was prepared by drying at 110°C for 4h and calcining at 550°C for 3h.

Abstract

The invention relates to an inferior gasoline hydrotreating catalyst and a preparation method and application thereof. The catalyst comprises the following active components in percentage by mass: 19 to 22 percent of WO3, 4 to 5 percent of NiO, 2 to 3 percent of P (on the basis of the mass of P2O5), 10 to 13 percent of MoO3, 1 to 2 percent of lithium or lanthanum (on the basis of oxides) and the balance of silicon-aluminum carrier. According to the preparation method, catalytic gasoline of which the mixed volume ratio is 3:1 and coker gasoline are hydrotreated under the action of the catalyst to remove sulfur and nitrogen, wherein the sulfur content of the mixed gasoline is 2,854 ug.g<-1>, the nitrogen content is 760 ug.g<-1>, the removal rate of the sulfur and the nitrogen is over 95 mass percent, and the content of the sulfur and the nitrogen in treated products is less than 50 ug.g<-1>.

Description

Technical field: [0001] The invention relates to an inferior gasoline hydrotreating catalyst and its preparation and application. Background technique: [0002] In order to meet the growing demand for light oil products to produce light oil products and improve economic efficiency, it is still necessary to greatly increase the secondary processing capacity, namely hydrocracking, catalytic cracking and coking. In addition, clean fuel standards have been continuously improved. From January 1, 2003, the quality of automobiles in Beijing, Shanghai, and Guangzhou must meet the World Fuel Standards Class II standard, and from 2006, automobiles in the above cities must To meet the Class III standard of the World Fuel Standard, other cities will move closer to the Class II standard of the World Fuel Standard. After December 31, 2009, the gasoline standard will adopt the National III standard, which puts forward stricter restrictions on harmful substances such as sulfur, olefins and ...
