This project aims at developing a predictive chemical kinetic model of secondary gas phase reactions of pyrolysis products from biomass and coal. For a better understanding of the chemistries involved in such a complex gas mixture over a wide range of operational condition, I tried to develop elementary reaction based kinetic model, which is so called detailed chemical kinetic model (DCKM). At first, it was very challenging to characterize compounds involved in primary pyrolysis products from naturally synthesized macromolecule such as coal and biomass as much as possible. However it was succeeded to develop a DCKM which include major reactions involved in cracking, partial oxidation, and steam reforming of multi-component gas mixture derived from coal and biomass pyrolyses. The DCKM originally developed in this project consists of more than 500 chemical species which include not only molecules but also radicals, and more than 8000 elementary reactions.
