During coal carbonization, the evolving volatile matters suffer cracking reactions giving more or less pyrolytic carbon. The purpose of this present study was to understand the formation of these deposits in order to be able to reduce this phenomenon. In a first step, the characterization of some carbonaceous deposits, sampled in various zones of coke ovens, has been carried out in order to confirm their origin. The influence of gas flow on the residence time of gas in the canal under arch crown was studied with a hydraulic cold model. To follow the kinetics of cracking reactions during a coking cycle, the measurement of the resistance of carbonaceous deposits formed on a specific probe was tested at laboratory scale and full scale. To determine the cracking conditions at full scale, the characterization of the canal under arch crown of some coke plants has been carried out.
