Problems solved by technology

[0008] Overall, although the current H 2 o 2 Oxidative desulfurization has developed a large number of various oxidation systems, but most of them are still far away from commercial application. Therefore, it is still necessary to develop new H 2 o 2 Oxidative desulfurization method to choose for commercial application

Abstract

The invention provides a fuel oil oxidation treatment method applicable to fuel oil desulfurization. Hydrogen peroxide and chlorine together react with fuel oil at the same time, and the fuel oil at the end of reaction is oxidation treated fuel oil. The fuel oil treated by the method is more easily desulfurized by a liquid-liquid extraction process.

Description

technical field [0001] The invention relates to a fuel oil oxidation treatment method applicable to fuel oil desulfurization, and belongs to the technical field of fuel oil refining in the petrochemical industry. Background technique [0002] With the development of economy and society, the consumption of fuel oil (gasoline and diesel oil, etc.) of various means of transportation is increasing day by day, and the pollution of exhaust emissions is becoming more and more serious to the environment, especially the current automobile exhaust emissions are making China Cities are facing unprecedented pressure on environmental protection. In this situation, the production and use of cleaner low-sulfur, ultra-low-sulfur or even sulfur-free fuels has become an important choice to control the exhaust pollution of vehicles. [0003] In the past two decades, fuel oil standards around the world have become more and more stringent on sulfur content, and reducing sulfur content is an imp...
