Introduction to the volatile matter of coal pitch
I. Introduction. Coal pitch is a widely used industrial raw material, and it has important application value in many fields. However, many people may not be aware of the properties of this material. In particular, the volatile content of coal pitch is one of the key factors affecting its application performance. This article will give a detailed introduction to the volatile content of coal pitch to help readers better understand the properties of this material.
2. Definition of volatile content of coal pitch.
The volatile content of coal pitch refers to the components that can be volatilized in coal pitch under specific conditions. These components mainly include light oil, phenol oil, anthracene oil, etc., which are easily volatile at high temperatures. The volatile content of coal pitch is one of the important indicators to evaluate its quality, and it has an important impact on the application performance of coal asphalt.
3. The volatile content of coal asphalt.
The volatile content of coal pitch is mainly a by-product of the coal coking process. In the high-temperature coking process, the organic matter in the coal will undergo pyrolysis and polycondensation reactions, producing a large number of volatile substances. These substances are further processed to form volatiles of coal pitch. Therefore, the volatile content and composition of coal pitch are closely related to the coking process, the properties of raw coal and other factors.
Fourth, the composition of volatiles of coal asphalt.
The volatile content of coal pitch is mainly composed of phenol oil, anthracene oil, naphthalene oil and other components. Among them, phenol oil and anthracene oil are the main components, which play a decisive role in the volatile content and properties of coal pitch. Naphthalene oil and other components are less abundant, but they also have a certain effect on some properties of coal pitch.
5. Application of volatiles in coal asphalt.
The volatile matter of coal pitch has high utilization value and can be used in many fields. For example, components such as phenol oil and anthracene oil can be used as chemical raw materials such as fuel oil and solventsNaphthalene oil and other components can be used as raw materials for chemical products such as dyes and pesticides. In addition, the volatile content of coal pitch can also be used in the production of waterproofing materials, coatings and other products.
VI. Conclusions. As an important industrial raw material, the characteristics of coal pitch have an important impact on the application performance. Among them, the volatile matter of coal asphalt is one of the important indicators to evaluate its quality, and it plays a decisive role in the application performance of coal asphalt. Understanding the volatiles, composition and application value of coal pitch will help to make better use of this material and promote the development of related industries. At the same time, the control of volatiles in the production process can improve the quality and stability of coal pitch and meet the application needs of different fields. Therefore, for enterprises and technicians engaged in the production and application of coal asphalt, it is necessary to have an in-depth understanding and grasp the relevant knowledge of the volatile content of coal asphalt.
