Application and research progress of carbonization consolidation of high temperature coal tar pitch binder in formed carbon material

High temperature coal tar pitch (HTCTP) has excellent wettability and cohesiveness, and can be used as binder. HTCTP binder can produce good consolidation with carbonaceous granular materials, so it has been widely used and studied in the preparation of different types of formed carbon material. The mechanical strength and physicochemical properties of formed carbon material are determined by the bonding performance and carbonization consolidation effect of HTCTP in high temperature process. In this paper, the general technological process and relative research progress of carbonization materials prepared with HTCTP as binder are reviewed, and the common mechanism and individual characteristics of carbonization consolidation of HTCTP in different application fields are combed. The factors affecting the performance of HTCTP and the mechanism of carbonation consolidation are also summarized. By analyzing the role and transformation process of different components of coal pitch in carbonization consolidation process, the related mechanism between the carbonization consolidation of HTCTP and the mechanical strength of formed carbon material and the key factors influencing the carbonization consolidation strength are revealed. The measures to strengthen the carbonization consolidation of HTCTP were proposed to enhance the application effect of carbonization consolidation in the preparation of formed carbon material.
