For the electric power generation by the woody biomass gasification, tar is incidentally formed at the same time. Partial combustion process is applicable to a reduction technique of the tar in the producer gas. During the partial combustion process, cracking and polymerization of tar occur simultaneously at the proximity of the inverse diffusion flame. This polymerization of tar into soot is a significant problem in the gas reformer with the partial combustion method. We focus attention on hydrogen abstraction in growth mechanism of polycyclic aromatic hydrocarbon (PAH) that is precursor of soot. The opposed-flow diffusion flame model (OPPDIF) with detailed elementary reaction mechanism is introduced to investigate reaction paths of toluene as a model tar. Main results are as follows. Cracking and polymerization of toluene start by hydrogen abstraction by H atom. The influence of hydrogen abstraction by OH radical is small in reactions of cracking and polymerization of toluene.
