There is not much known about the reactivity of hydrocarbon soot to oxygen and NO. According to the chemical and structural properties of one soot obtained from acetylene pyrolysis, SEVACARB MT and CABOT carbon blacks were selected to perform a reactivity study. The properties of the materials were determined through ultimate and proximate analysis as well as SEM, TEM and XRD techniques. A study of the oxidation of the three materials is performed for different oxidation conditions of temperature (1123-1273 K) and oxygen concentration (100-1000 ppmv). The reaction of acetylene soot with NO and SEVACARB MT carbon black is carried out at 1373 K with 1800-3000 ppmv NO. Results are compared to analyze their reactivity similarities and the possibility of using carbon blacks as acetylene soot substitutes in laboratory work.
