Study of Coke Making Experiments With Different Waste Plastic Blending

QIAN Hui,ZHOU Yu-sheng(Iron-Making Innovation Department,Baosteel Research Institute,Baoshan Iron and Steel Co.,Ltd.,Shanghai 201900,China)  
The cooperating effect between individual coal and waste plastic was studied during coke making process.Coke making experiments with PE,PP,PET,PS,and PVC after dechlorination were carried out in 20kg coke oven.The influences of different waste plastic on the coke strength,CRI and CSR were studied based on co-carbonization behavior between coal and waste plastic by using thermo gravimetric analyses as well.The results demonstrate that the temperature range of decomposition and DTG curve distribution of different individual coal and waste plastic determined the coke properties.Coke strength produced from high rank coal decreased after blending with all kinds of waste plastic.Among all tested waste plastics,PS and PET showed worse co-operation with coals in coke making process.
