Catayst for hydrogenation refining metal sulfer phosphorus compound

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....

Problems solved by technology

For more than 60 years, although sulfide catalysts have been continuously improved, their activity still cannot meet the requirements of increasingly stringent environmental regulations

However, among transition metal phosphides, except nickel phosphide, other metal phosphides have unsatisfactory hydrodesulfurization and denitrification activities.
