Embodiment 1

[0021] 90wt% coarse-porous silica powder and 10wt% magnesium oxide powder are used to prepare the catalyst body by rolling ball molding method, and it is ready for use after calcination at 650oC. Use the mixed solution of ammonium molybdate, nickel nitrate, diammonium hydrogen phosphate and ammonia water to impregnate with equal volume, load 6wt% Mo, 2.1wt% Ni and 5.5wt% P, dry and roast in 450oC air for 2 hours to get Catalyst A.

Embodiment 2

[0023] Zirconium oxychloride is hydrolyzed in ammonia water, treated under 120oC hydrothermal condition for 48h, filtered, washed, dried, and then prepared by kneading and extruding zirconia catalyst carrier. Catalyst B was obtained by impregnating with a mixed solution of ammonium molybdate, phosphorous acid and ammonia water, loaded with 8.2wt% Mo and 5.7wt% P, dried and calcined in air at 380oC for 2 hours.

Embodiment 3

[0025] Fully mix 90g of coarse-pored silica and 30g of boehmite, add 1:1 nitric acid and appropriate amount of water, knead and extrude, keep healthy at room temperature, dry at 120oC overnight, and roast in 550oC air atmosphere for 4 hours to obtain the catalyst carrier. The mixed solution of nickel nitrate, phosphoric acid, cerium nitrate and nitric acid was impregnated with equal volume, loaded with 7.0wt% Ni, 1.5wt% Ce and 3.2% P, dried and calcined in 450oC air for 2h to obtain catalyst C.

Abstract

The present invention relates to a condensed ring aromatic saturation catalyst with strong raw material adaptability, and mainly solves the problems that a catalyst in the prior art is not strong in material adaptability, and cannot simultaneously treat sulfur-containing and sulfur-free raw materials. The condensed ring aromatic saturation catalyst comprises the following components by weight: a) 0.2-35wt% of at least one of Group VIII or Group VIB metals; b) 0.2-25wt% of phosphorus; and c ) 40-99.6wt% of a carrier, by the technical scheme, the problem is well solved, and the catalysts can treat sulfur-containing and sulfur-free raw materials, and can be used in condensed ring aromatic saturation industrial production.

Description

technical field [0001] The invention relates to a fused-ring aromatic hydrocarbon saturation catalyst with strong raw material adaptability, in particular to a catalyst capable of effectively saturating bicyclic aromatic hydrocarbons, tricyclic aromatic hydrocarbons or sulfur-containing or sulfur-free raw materials containing condensed-ring aromatic hydrocarbon mixtures. Background technique [0002] Fused-ring aromatic hydrocarbons refer to a class of hydrocarbons including naphthalene-based bicyclic aromatic hydrocarbons, anthracene and phenanthrene-based tricyclic aromatic hydrocarbons. Coal tar, a by-product of coal coking, generally contains 10 wt% naphthalene. The 200-250oC fraction obtained when distilling coal tar is called naphthalene oil fraction, which contains about 50wt% naphthalene. With the development of direct coal liquefaction industry, the chemical utilization of a large amount of coal liquefied oil is also a difficult problem. In the range of 200-360oC f...
