In this study, the influence of microwave energy on the chemical characteristics of the gases and oils produced by decomposing LDPE-LLDPE-EVA copolymer was evaluated. In addition, the result was compared using conventional heating. The selectivity of C20+ products was very low when pyrolysis was carried out at 250Wor higher microwave energy, while conventional pyrolysis showed a wide range of product distribution from C1 to C32. The selectivity to C2 and C3 hydrocarbon increased with increasing of microwave energy. The olefin fraction in C 2-C4 went up to 81.5 wt % microwave-induced pyrolysis, which was greater than that for conventional pyrolysis. Microwave-induced pyrolysis could be a more favorable option than conventional pyrolysis in generating light hydrocarbon from a polymer mixture.
