example 1

[0029] Take by weighing 2000 grams of aluminum hydroxide powder (dried rubber powder produced by Changling Branch Catalyst Factory, 70% by weight on a dry basis) and 299 grams of silica sol (Qingdao Ocean Chemical Plant product) containing 25% of silicon dioxide. Machine extruded into a butterfly-shaped bar with a circumscribed circle diameter of 1.3 mm, the wet bar was dried at 120° C. for 4 hours, and then calcined at 600° C. for 3 hours to obtain carrier S1. The silicon oxide content in the carrier S1 was 5.0% by weight.

[0030] Weigh 200 grams of carrier S1, impregnate the carrier with 176 ml of an aqueous solution containing 9.2 grams of ammonium fluoride (analytical grade, product of Beijing Chemical Plant) for 2 hours, dry at 120°C for 3 hours, and roast at 500°C for 3 hours to obtain fluorine-containing Silica-alumina support. With 172 milliliters of the aqueous solution containing ammonium paramolybdate (chemically pure, Beijing chemical factory product) 14.2 grams i...

[0032] Weigh 200 grams of carrier S1, impregnate the carrier with 176 ml of an aqueous solution containing 26.8 grams of ammonium fluoride for 2 hours, dry at 120°C for 3 hours, and calcinate at 400°C for 5 hours to obtain a fluorine-containing silica-alumina carrier. Impregnate the carrier with 172 ml of an aqueous solution containing 17.9 grams of ammonium paramolybdate for 3 hours, dry at 250°C for 5 hours, and then impregnate the carrier with 166 ml of an aqueous solution containing 26.2 grams of nickel nitrate, 86.7 grams of ammonium metatungstate, and 9.2 grams of phosphoric acid3 hour, and dried at 120° C. for 8 hours to obtain catalyst C2. The composition of catalyst C2 after calcination is listed in Table 1.

example 3

[0034] Weigh 200 g of carrier S1, impregnate the carrier with 176 ml of an aqueous solution containing 9.8 g of ammonium fluoride for 2 hours, dry at 120° C. for 3 hours, and calcinate at 400° C. for 3 hours to obtain a fluorine-containing silica-alumina carrier. The carrier was impregnated with 172 ml of an aqueous solution containing 25.1 g of ammonium paramolybdate, 29.6 g of nickel nitrate, 67.9 g of ammonium metatungstate, and 12.1 g of phosphoric acid for 3 hours, dried at 120°C for 8 hours, and calcined at 450°C for 4 hours to obtain catalyst C3. The composition of catalyst C3 after calcination is listed in Table 1.

Abstract

An F and P contained hydrocatalyst with silicon oxide-aluminum oxide as its carrier contains nickel oxide (1-10 Wt%), molybdenum oxide and tungsten oxide (10-50), F (1-10) , phosphorus oxide (0.5-8) and carrier (rest). It has high hydrorefining performance. It is prepared by introducing F, P, Mo, Ni and W to carrier.

Description

technical field [0001] The invention relates to a hydrogenation catalyst and its preparation, more specifically to a fluorine-phosphorous hydrogenation catalyst with silicon oxide-alumina as a carrier and its preparation. Background technique [0002] Under the hydrogenation reaction conditions, the contact of the hydrocarbon feedstock with the catalyst may occur including: hydrogenation, hydrodesulfurization, hydrodenitrogenation, hydrodemetallization, hydrodearomatization, hydroisomerization, hydrodewaxing, hydrogenation Reactions such as hydrocracking and moderate hydrocracking. The catalysts therein are generally formed by the carrier supporting metal components of Group VIB and Group VIII. The hydrogenation active metal component is usually selected from Co or Ni-Mo or Co or Ni-W, and the carrier is usually selected from alumina, silica-alumina and their modified products. These catalysts can be prepared by impregnating the support with an aqueous solution containing ...
