Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions.

[0013] Preparation of catalyst precursor:

[0014] Taking the preparation of silica-supported molybdenum-sulfur-phosphorus catalyst precursor by co-impregnation method as an example, MoO 3 The loading amount is 40% (mass). Take by weighing 3.65 grams of ammonium molybdate ((NH 4 ) 6 Mo 7 o 24 .4H 2 O) and 2.729 grams of diammonium hydrogen phosphate ((NH 4 ) 2 HPO 4 ), add 10 ml of deionized water, and dissolve to make an impregnation solution. Weigh 3 grams of porous silica, add impregnation solution, and impregnate at room temperature for 12 hours. The slurry was dried at 120°C for 12 hours, and then calcined in air at 500°C for 5 hours to obtain a dark blue solid.

[0015] Catalyst preparation:

[0016] The dark blue catalyst precursor is made into 0.3-0.5 mm particles by tableting, and 0.2 g is weighed and loaded into a fixed-bed rea...

Abstract

The present invention relates to a melattothiophosphide hydrofining catalyst to the field of coal processing, petroleum processing and petrochemical technology. It the concrete, it relates to a solid catalyst for hydrofining petroleum fractions (gasoline, kerosene and diesel oil, etc.). Said invention also provides the concrete steps of said catalyst preparation method.

Description

technical field [0001] The invention belongs to the fields of coal processing, petroleum processing and petrochemical industry, and relates to a solid catalyst used in the hydrorefining process of petroleum distillate oil (gasoline, kerosene, diesel oil, etc.). Background technique [0002] With the continuous and rapid development of my country's economy and the rapid increase of car ownership, oil consumption has increased rapidly in recent years. In 2003, my country's oil consumption reached 260 million tons, including 91 million tons of imported crude oil, making it the world's second largest oil consumer after the United States. It is predicted that my country's crude oil imports will reach 150 million tons and 200 million tons in 2010 and 2015, respectively. The produced fuel oil produces a large amount of SOx and NOx after combustion, which will seriously pollute the atmospheric environment, not only damage people's health, but also cause disasters such as acid rain....
