Hydrogenated tail oil in the field of chemical production raw materials in the nature and use of

1. Introduction

Hydrogenated tail oil is a by-product produced in the petrochemical process, mainly from hydrocracking, hydrogenation refining and other processes. With the rapid development of petrochemical industry, the output of hydrogenation tail oil is increasing year by year. Because of its unique properties and wide range of applications, hydrogenation tail oil plays an important role in the field of chemical production raw materials. In this paper, the properties, production methods, main uses and development trends of hydrogenation tail oil will be introduced in detail. Properties of

2. hydrogenation tail oil

hydrogenation tail oil is mainly composed of hydrocarbons, including alkanes, naphthenes, aromatic hydrocarbons, etc. Its properties mainly depend on the nature of the feedstock oil and the hydrogenation process conditions. Generally speaking, the hydrogenated tail oil has high density, moderate viscosity, high thermal stability and oxidation resistance. At the same time, due to the hydrogenation treatment, the content of sulfur, nitrogen and other impurities in the hydrogenation tail oil is low, which has good environmental performance.

3. hydrogenation tail oil production method

hydrogenation tail oil production mainly uses hydrocracking and hydrogenation refining process. These processes are mainly hydrotreating the raw oil under the conditions of high temperature, high pressure and hydrogen, so that the sulfur, nitrogen and other impurities are effectively removed, and the quality of the oil is improved. In the production process, it is necessary to select appropriate process conditions and catalysts according to the nature of the raw oil and product requirements. The main uses of

4. hydrogenation tail oil

1. as fuel oil

hydrogenation tail oil can be used as fuel oil, because of its high calorific value and low sulfur, nitrogen and other impurities, so it is a more environmentally friendly fuel. At the same time, the hydrogenation tail oil has moderate viscosity and is easy to transport and burn, so it is widely used in electric power, metallurgy and other industries.

2. as a chemical raw material

hydrogenation tail oil can also be used as a chemical raw material for the production of various chemical products. For example, hydrogenated tail oil can be used as raw material to produce lubricating oil, paraffin wax, asphalt and other products. In addition, the hydrogenation tail oil can be further processed to produce benzene, toluene, xylene and other aromatic hydrocarbon products, which are widely used in plastics, rubber, fibers and other fields.

5. development trend

With the continuous improvement of environmental awareness and the rapid development of the petrochemical industry, the application prospect of hydrogenated tail oil is becoming more and more broad. In the future, the production technology and application fields of hydrogenated tail oil will continue to be expanded, and its position in the field of chemical production raw materials will become more important. At the same time, with the continuous advancement of technology and the continuous improvement of application requirements, the production process and product quality of hydrogenated tail oil will also be further improved.

6. conclusion

In conclusion, as an important raw material for chemical production, hydrogenation tail oil has a wide range of uses and good environmental performance. In the future, with the continuous advancement of technology and the continuous improvement of application requirements, the production process and product quality of hydrogenated tail oil will be further improved, and its position in the field of chemical production raw materials will become more important.
