Review of Coal tar preparation and processing technology

摘要

To generate coal tar with coal is the key technology of coal chemical industry, the generated coal tar is one of the important industry fuel and chemistry raw materials, and more attentions were attracted in coal tar preparation and processing technologies in recent years. Therefore, review of the updated technologies is developed at the present work. As for coal tar preparation technology, coal carbonization processing and coal hydropyrolysis are mature and has been applied to industry production. In comparison, hydrogenation of coal tar is just at the development. In term of coal tar processing technology, the present leading directions are how to manufacture clean fuel as well as phenol. Based on the status of coal tar preparation and processing technology, resources recycling use isn't enough, consumptions of per ton coal is higher, environmental pollution is serious, and deep processing technology of coal tar needs to be raised.
