Reaction mechanism for partial oxidation of biomass tar

By combining the detailed reaction mechanism proposed by Richter et al.for hydrocarbon combustion and the removal methods of tar oil from biomass gasification by partial oxidation,a detailed reaction mechanism was put forward for partial oxidation of biomass tar.A comparison with the experiment results obtained by Jess confirmed the model's rationality and accuracy.Phenol that was chosen as a model component for biomass tar was converted i.e.partial combustion at condition of ER=0—0.2.The results show that oxygen can promote conversion of tar oil and its reaction rate,and proper oxygen content leads to higher production of combustible gases.Based on typical PAHs production rates obtained by ROP analysis it is found that cyclopentadiene plays an important role in the formation and growing of PAHs and active radicals such as H and OH promote tar cracking.
