Coal tar pitch is the residue after extraction of the light components from coal tar. The research of modified coal tar pitch has been continuously developing due to more stable performance, higher carbon content and lower price. In this paper, characteristics and composition of coal tar pitch were summarized. And main application of modified coal tar pitch in carbon products, graphite electrode, needle coke, mesophase pitch, carbon fiber, paint and fuel oil was introduced.
