A poly-generation system with CO2 capture and O2/CO2/H2O blown gasifier using various fuels such as coal, waste plastic and biomass has been developed. There is concern that the gasification of waste plastics will produce more tar and soot, which can cause equipment problems, than the conventional coal gasification. In this study, the formation behavior of tar and soot derived from plastics in a gasification atmosphere was investigated by elementary reaction analysis using a detailed chemical reaction mechanism. As a result, the calculated concentration of the major gas compositions and soot yield values agreed with the experimental ones. The results of the reaction pathway analysis also revealed the mechanism of PAH formation
