In this study, the CO2 co-gasification characteristics of pyrolytic oil distillation residue and biochar under different reaction temperatures were investigated by thermogravimetric analyzer (TGA). The influence of blend ratio on co-gasification synergy was adequately characterized by correlating the evolution of chemical structure and active AAEMs. The results indicated that increasing proportion of pyrolytic oil distillation residue could effectively improve gasification reactivity of biochar and enhance synergistic behaviors during co-gasification process, whereas the raising reaction temperature dwindled the enhancement of co-gasification reactivity and mutual promotion between individual samples. Moreover, three gasification kinetic models suggested that the lowest apparent activation energy (181.49~182.72 kJ/mol) among blends was obtained by 70 wt% additions of pyrolytic oil distillation residue. Furthermore, the results of Raman and ICP-AES analysis well related to the co-gasification synergy. The migration of active AAEMs and evolution of carbon structure had a pronounced influence on synergistic effect as co-gasification reaction progressed.
