摘要
High-temperature coal tar (HTCT) is an important raw material for obtaining value-added aromatics. However, effective utilization of HTCT is not optimistic because of backward processing technology and higher energy consumption, resulting in fewer product types and lower purity. Accordingly, value-added utilization (VAU) of HTCT should be paid urgent attention. In order to realize VAU of HTCT, deep processing methods were systematically discussed. This paper mainly discusses the source, composition, research status, separation method, and upgrading of HTCT along with the utilization of coal tar pitch. Subsequently, the comprehensive processing route for VAU of HTCT was proposed. HTCT research ideas are put forward in combination with future research directions. We hope that this review will add to the ongoing discussions on the VAU of HTCT.
