Coal-Tar Pitch - an overview ScienceDirect Topics

The process in which the carbonaceous binder, usually coal tar pitch or petroleum pitch, as part of a shaped carbon mix is converted to carbon yielding a rigid carbon body by the slow application of heat. The process can take as little as 14 days in coarse-grained, electrothermic grades (low binder level) and as long as 36 days in ultra-fine ...

Modeling of Oxidation Process of Coal Tar Pitch in ...

2019-7-7  In this paper, a three-dimensional numerical model has been developed to study the process of oxidative weight increment of coal tar pitch in a rotating kiln. Based on the two-fluid method, the gas phase is modeled by realizable k - ε turbulent model and the solid phase is modeled by kinetic theory of granular flow. The dense gas-solid flow, heat transfer, and oxidation reaction for the bed ...
