Embodiment 1

[0029] (1) Preparation of hydrocracking catalyst carrier

[0030]Put 20gY molecular sieve, 8gSAPO-34 molecular sieve, 80g amorphous silica alumina, and 4g microcrystalline cellulose into the rolling machine for rolling. After rolling for 15 minutes, add guar gum (0.5%) and nitric acid (2.5%) The aqueous solution was rolled into a paste and extruded. The extruded strips were dried at 120°C for 3 hours and calcined at 550°C for 3 hours to obtain carrier Z1. The physical and chemical properties of the carrier and molecular sieve are shown in Table 1.

[0031] (2) Catalyst preparation

[0032] The carrier Z1 was impregnated with an equal volume of impregnation solution containing Mo, Ni, and P, dried at 120°C for 3 hours, and calcined at 480°C for 2 hours.

Embodiment 2

[0034] (1) Preparation of hydrocracking catalyst carrier

[0035] Put 10gY molecular sieve, 5gSAPO-34 molecular sieve, 90g amorphous silica alumina, and 3g microcrystalline cellulose into the rolling machine for rolling. After rolling for 15 minutes, add guar gum (0.6%) and nitric acid (2.3%) The aqueous solution was rolled into a paste and extruded. The extruded strips were dried at 110°C for 3 hours and calcined at 500°C for 4 hours to obtain carrier Z1. The physical and chemical properties of the carrier and molecular sieve are shown in Table 1.

[0036] (2) Catalyst preparation

[0037] The carrier Z2 was impregnated with an equal volume of impregnation solution containing Mo, Ni, and P, dried at 100°C for 3 hours, and calcined at 450°C for 2 hours.

Embodiment 3

[0039] (1) Preparation of hydrocracking catalyst carrier

[0040] Put 23gY molecular sieve, 10gSAPO-34 molecular sieve, 60g of amorphous silica-alumina, and 2g of microcrystalline cellulose into the rolling machine for rolling. After rolling for 12 minutes, add guar gum (0.2%) and nitric acid (2.3%) The aqueous solution was rolled into a paste and extruded. The extruded strips were dried at 90°C for 5 hours and calcined at 580°C for 3 hours to obtain the carrier Z3. The physical and chemical properties of the carrier and molecular sieve are shown in Table 1.

[0041] (2) Catalyst preparation

[0042] The carrier Z3 was impregnated with an equal volume of impregnation solution containing Mo, Ni, and P, dried at 100°C for 3 hours, and calcined at 450°C for 2 hours. The finally obtained catalyst was designated as C-3.

Abstract

The invention discloses a hydrocracking catalyst carrier as well as a preparation method and application thereof. The carrier contains a Y molecular sieve and an SAPO-34 molecular sieve, based on thecarrier, the weight content of the Y molecular sieve is 2-35wt%, and the content of the SAPO-34 molecular sieve is 2-25wt%. The preparation method of the carrier comprises the following steps: uniformly mixing materials containing a Y molecular sieve and an SAPO-34 molecular sieve, adding an acidic solution, molding, drying, and roasting to obtain the hydrocracking catalyst carrier. A catalyst prepared from the carrier has high reaction activity, medium oil selectivity and excellent product properties in the hydrocracking reaction process.

Description

technical field [0001] The invention relates to a hydrocracking catalyst carrier and its preparation method and application, in particular to a high and medium oil type hydrocracking catalyst carrier and its preparation method and application. Background technique [0002] As the demand for middle distillates in the international oil market continues to increase, more middle distillates need to be obtained from heavy distillates, especially aviation kerosene, and the hydrocracking process is the key to lightening heavy oil One of the means. The process has the characteristics of strong raw material adaptability, good product quality, strong adjustment flexibility, high yield of middle distillate, and flexible product structure, which makes the status of hydrocracking technology more and more important, especially for the current problems faced by our country. Due to the shortage of petroleum resources, increasingly stringent environmental protection requirements, and the fa...
