Abstract

The invention relates to a hydrotreatment catalyst and an application thereof. The catalyst comprises a carrier and hydrogenation active metal components loaded on the carrier. The catalyst is characterized in that the hydrogenation active metal components are nickel, cobalt and molybdenum. In terms of oxides based on the weight of the catalyst, the sum of the contents of nickel and cobalt is 2-10wt% and the content of molybdenum is 10-30wt%, wherein the atomic ratio of nickel to cobalt is 1.4-10. The catalyst is suitable to be used in hydrocarbon oil hydrotreatment for preparing clean oil products.

Description

technical field [0001] The invention relates to a hydrotreating catalyst and its application. Background technique [0002] Nitrogen oxides (NOx) in vehicle exhaust X ) not only form acid rain in cities and surrounding areas, but also severely damage the earth’s ozone layer; the particulate matter (PM) in the exhaust gas contains a variety of substances that are listed as possible carcinogens by international research institutions; sulfur compounds in diesel oil are harmful to automobiles. The impact of pollutant emissions is also great, especially for NO X and the production of PM have a significant promotion effect, and the sulfur oxides (SO X ) is not only the main cause of acid rain but also the poisoning of motor vehicle exhaust purification catalysts. Aromatics in diesel also have many adverse effects on its properties. Aromatics will make carbon monoxide and NO in automobile exhaust X The emission of pollutants such as PM and PM will increase, and aromatics will a...
