Background. As important chemical raw materials, coal asphalt and modified asphalt are widely used in many fields such as road construction, waterproofing materials, coatings and adhesives. Research on coal asphalt to bitumen technology, aiming to improve resource utilization efficiency, while meeting environmental protection and performance needs. In this context, the characteristics of coal asphalt, the development process of modification technology, the advantages and disadvantages of modification methods, as well as the current views and challenges, are of great significance for promoting technological progress in this field.
Coal pitch features.
Coal pitch is a residue obtained by distillation of coal tar, which has the characteristics of high viscosity, high flash point and low water content. Its complex composition and the presence of a variety of aromatic hydrocarbon compounds and heteroatomic compounds are characteristic of coal pitch that face certain challenges in processing and application.
The development process of modified asphalt technology.
The development of coal asphalt upgrading technology has gone through many stages. With the joint efforts of foreign researchers, the modification technology has been continuously innovated and improved, and the main achievements include acid-base treatment, hydrocracking and other methods. The development of these technologies has made the effect of coal asphalt pouring into the modification continue to improve, and the application field has also been expanded.
Upgrading technology and methods.
At present, the commonly used methods of coal asphalt modification mainly include acid-alkali treatment, hydrocracking, etc. Acid-base treatment improves the stability and processability of coal pitch by adjusting its acid-base properties. Hydrocracking is the introduction of hydrogen to crack the macromolecular compounds in the coal pitch to produce low-molecular weight compounds, thereby improving its performance. Each method has advantages and disadvantages, and the choice should be based on actual needs.
A roundup of perspectives. In the research of coal asphalt modification technology, environmental protection and resource utilization efficiency have become the focus of attention. In terms of environmental protection, the upgrading process should reduce pollutant emissions and improve the efficiency of wastewater and waste gas treatment. In terms of resource utilization efficiency, attention should be paid to how to increase the added value of coal pitch and maximize the utilization of resources. However, in practice, these perspectives may face technical, economic, and other challenges.
Conclusion. In summary, the research on coal asphalt to asphalt conversion technology is of great significance for improving resource utilization efficiency and promoting environmental protection. Through continuous innovation and improvement of related technologies, it is expected to promote the continuous development and progress of this field on a global scale. At the same time, facing challenges such as environmental protection and resource utilization efficiency, it is necessary for the industry to work together inside and outside the industry to explore effective solutions and contribute to the sustainable development of coal asphalt to asphalt conversion technology.
