摘要： In the present study, nitrogen-rich wood waste underwent the thermo-oxidative degradation based on an entrained flow reactor with a mixture of oxygen and argon as the reaction agent. In addition, by comparing the results from pine and corncob, the fuel-nitrogen transformations and distributions from the thermo-oxidative degradation of wood waste were analyzed. Furthermore, the effects of three operational parameters (i.e., temperature, equivalence ratio and oxygen concentration) on the fuel-nitrogen transformations and distributions from the thermo-oxidative degradation of wood waste were determined. According to the results, the fuelnitrogen when undergoing the thermo-oxidative degradation of wood waste was primarily converted into the gaseous product. Thus, N2 was determined as the major gaseous nitrogen-containing product, taking up nearly 76?96 % of the total nitrogen. HCN and NH3, two primary gaseous nitrogenous pollutants generated in the thermo-oxidative degradation of wood waste, exhibited the significantly higher concentrations than those generated from the thermo-oxidative degradation of pine and corncob, and their max concentrations reached 1180 and 1060 mg/m3. Furthermore, the distributions of nitrogen-containing compounds in the gas, the char and the tar were observed to be noticeably impacted by temperature, equivalence ratio and oxygen concentration. Besides, the yield of N-tar decreased from 17.9 to 0% and 15.65 to 5.67 %, and the N-pyrrole in char increased from 19 to 76.6 % and from 68.9?76.5% with the increase in temperature and equivalence ratio.
