preparation example Construction

[0040] The present invention also provides a method for preparing the aforementioned heavy oil hydrogenation catalyst, comprising: mixing the inorganic heat-resistant oxide precursor, the non-metal additive precursor and the molding aid to obtain a mixture, and performing molding treatment; Carry out one impregnation in a solution containing a nickel source, the product after the one impregnation is dried and calcined at a temperature of 600°C to 800°C for 1h to 10h to obtain a carrier; and the carrier is impregnated in a solution containing an active component Secondary impregnation, the product after the second impregnation is dried and then activated at a temperature of 300° C. to 550° C. to obtain the heavy oil hydrogenation catalyst.

[0041] Tests have shown that in the preparation method of the present invention, only by calcination at a temperature of 600-800° C. for 1-10 hours can the carrier with the aforementioned spinel structure be formed. If the calcination tempe...

Embodiment 1

[0060] This example is used to illustrate the preparation method of the boron-containing heavy oil hydrogenation catalyst of the present invention.

[0061] 1) Mix the pseudoboehmite dry rubber powder RPB100 produced by 1 kilogram of Changling Catalyst Factory and 30 grams of fenugreek powder, and mix the mixture with 1.2 liters of sulfuric acid 21.6 grams per liter and 14.1 grams of boron at room temperature. The mixed aqueous solution of sulfuric acid and boron oxide per liter is mixed evenly, kneaded into a plastic body on a twin-screw extruder, and then extruded into a Φ1.1mm butterfly strip. After the wet strip is dried at 120°C for 3 hours, it is kept at a constant temperature of 800°C. 4 hours to obtain the vector.

[0062] 2) Weigh 100 grams of the above-mentioned carrier, impregnate it with 120 milliliters of a mixed solution of basic nickel carbonate and phosphoric acid containing NiO 30 g / L for 1 hour, dry it at 110° C. for 4 hours, and roast it at 630° C. for 3 hou...

Abstract

The invention provides a heavy oil hydrogenation catalyst containing a non-metal auxiliary agent, the heavy oil hydrogenation catalyst comprises a carrier and an active component loaded on the carrier, the carrier comprises an inorganic heat-resistant oxide, nickel oxide, a compound of the inorganic heat-resistant oxide and the nickel oxide and the non-metal auxiliary agent, the non-metal auxiliary agent is selected from silicon and / or boron, and when the carrier is measured by a diffuse reflection ultraviolet-visible spectrum, the absorbance at 630 nm and 500 nm is F630 and F500 respectively, and the ratio Q of F630 to F500 is 1.3-3.0; the active component comprises at least one group VIB metal, and the content of the active component is 8%-30% by oxide on the basis of the total weight of the heavy oil hydrogenation catalyst; wherein in a Raman spectrum of the heavy oil hydrogenation catalyst, the intensity of a characteristic peak near 940 cm <-1> and the intensity of a characteristic peak near 840 cm <-1> are I940 and I840 respectively, and the ratio K of I940 to I840 is 1.0-2.4. The heavy oil hydrogenation catalyst disclosed by the invention has excellent activity and stability, the activity and stability of the catalyst can be further improved by the contained non-metal additive, and the heavy oil hydrogenation catalyst has a good application prospect.

Description

technical field [0001] The invention relates to the field of catalysts, in particular to a heavy oil hydrogenation catalyst containing non-metal additives, a preparation method and application thereof. Background technique [0002] Heavy oil processing, especially the deep processing of residual oil, not only helps to improve the utilization rate of crude oil, alleviate the tense trend of energy supply, but also reduce environmental pollution and realize efficient and clean utilization of energy. [0003] For heavy crude oil, pretreatment by hydrogenation process and then secondary processing can not only increase the yield of light oil products, but also reduce the content of sulfur, nitrogen and other pollutants in the oil products, so it is widely used in the market The demand for light oil products continues to increase, and today's environmental protection regulations tend to be stricter, and they are generally favored by refiners. Compared with light oil products, hea...
