  • Coking an overview ScienceDirect Topics

    Coal can be coking or noncoking; this is partially determined by the caking property of coal. Caking is determined by heating the coal to a certain temperature in the absence of air and, if it leaves a solid residue behind upon cooling, it is considered caking coal [ 40,43,44 ].

  • A relationship for the evaluation o coking values of

    Abstract. A relationship has been proposed to evaluate the coking values of coal tar pitches from the knowledge of their three other characteristics, namely, softening point, benzene insolubles content and quinoline insolubles content. It has been tried on 44 self-prepared coal tar pitches and 18 others obtained from the literature, possessing

  • Kinetic modelling of coking coal fluidity development

    2020-3-10 · When coking coal is heated, it becomes soft in the temperature range 385–450 °C. The temperature range within which the coal forms a plastic mass very much depends on its chemical composition. Upon raising the temperature further, the plastic mass begins to harden, producing solidified, porous coke.

  • Kinetic modelling of coking coal fluidity development

    2020-3-10 · Coal plasticity is a phenomenon directly affecting the creation of coke structure. It is very much a time- and temperature-dependent transformation of the coal matrix, which allows changing the physical phase from solid to liquid-like and again into solid of different properties. The coking process, particularly in a plasticization temperature range, can be considered as a non-isothermal
