Application
1 used as fuel, because of its solid components, it is usually mixed with heavy oil or made into slurry, which can partially replace heavy oil.
2 for the production of carbon electrode, the degree of carbon graphitization in coal tar pitch is relatively high. It can be used as the electrode material and can be used as the wetting agent and binder. It has many kinds of products and involves a wide range of products. It is the main use of coal tar pitch.
3 coatings, mainly processed and processed, are used for building and tubing waterproof coatings. Epoxy coal tar coating is one of the most widely used.
4 road and building materials are generally used in combination with petroleum asphalt. There is an obvious difference in quality and durability between coal tar pitch and petroleum asphalt. Coal tar pitch is poor in plasticity, poor in temperature stability, crisp in winter, softening in summer, and fast in aging. In addition, coal tar bitumen has many harmful substances, many of which are very harmful to the human body. After being treated harmlessly, it will be more environmentally friendly.
5 needle coke, activated carbon, carbon fiber and other high value-added products. Coal tar pitch has high residual carbon value, graphite formation and processing easily, while needle coke and carbon fiber are high end materials with high added value. Coal tar is used as raw material to turn waste into treasure.
