Coal carbonization process is strongly affected by the presence of metaplast components. In order to achieve an effective generation of metaplast, transferable hydrogen in coal, which was measured by the reaction of coal with anthracene at 420℃ for 5min, could be a key factor. Consumption of the transferable hydrogen with the heat treatment in an open system was largely different from that in a batch system. In a real coke oven, heating system is semi-batch type so that the authors would discuss plastic behavior of coal in a batch system by referring to the pyrolytic behavior including action transferable hydrogen.
