The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.
