Separating Techniques and Application of Coal Tar

This paper summarizes the present state and the advance of coal tar far - processing technique, and points out the problems in this field. The separating techniques used in coal tar separation such as distillation, crystallization, adsorption, membrane isolation and solvent extraction are generalized systematically. New technique of solvent extraction on coal tar far - processing is pointed out, and this new technique can conquer the disadvantages of traditional technique, and will promote the development of coal tar far - processing industry.
