Coal Coking Processing Wastewater

  • Advanced treatment of biologically pretreated coking .

    The raw coking wastewater was collected from a coking plant in Shanxi Province of China. An anaerobic–anoxic–oxic (A 1–A 2–O) process was used to treat this wastewater in our laboratory. The wastewater used in this work was the effluent of this A 1–A 2–O process. The characteristics of wastewater used in the experiments are listed .

  • Use of Waste Plastics in Coke Oven: A Review | SpringerLink

    Coke is produced in a coke oven by carbonizing (heat treating without oxygen at high temperature) coal. Waste plastics composed of carbon and hydrogen are converted to coke, COG and hydrocarbon oil like coal in the coking chamber. In this process, collected plastic waste is agglomerated and charged into the coke oven with coal.
