摘      要：This paper investigated the nanostructure and oxidation reactivity of soot generated from biofuel 2,5-dimethylfuran pyrolysis with different CO_(2) additions and different temperatures in a quartz tube flow *** morphology and nanostructure of soot samples were characterized by a low and a high resolution transmission electron spectroscopy(TEM and HRTEM)and an X-ray diffraction(XRD).The oxidation reactivity of these samples was explored by a thermogravimetric analyzer(TGA).Different soot samples were collected in the tail of the *** the increase of temperature,the soot showed a smaller mean particle diameter,a longer fringe length,and a lower fringe tortuosity,as well as a higher degree of ***,the variation of soot nanostructures resulting from different CO_(2) additions was not *** with 0%,50%,and 100%CO_(2) additions at one fixed temperature,the soot collected from the 10%CO_(2) addition has the highest degree of graphization and *** three temperatures of 1173 K,1223 K,and 1273 K,the mean values of fringe length distribution displayed a ranking of 10%CO_(2)100%CO_(2)50%CO_(2) while the mean particle diameters showed the same ***,the oxidation reactivity of different soot samples decreased in the ranking of 50%CO_(2) addition100%CO_(2) addition10%CO_(2) addition,which was equal to the ranking of mean values of fringe tortuosity *** result further confirmed the close relationship between soot nanostructure and oxidation reactivity.
