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 reaction in growth mechanism of poly cyclic aromatic hydrocarbon (PAH) that is precursor of soot. The Opposed-flow Diffusion Flame model (OPPDIF) is introduced to investigate the effects of hydrogen and steam addition to the oxidizer on PAH growth. The calculation results show that forward reaction of H abstraction reaction is inhibited by the hydrogen addition.
