Tóm tắt

 The oxidation kinetics for products of fast pyrolysis at low temperatures (<
 600�C) are not well known. These will be important in effort to model autothermal pyrolysis, which has been recently developed to intensify the process, but which occurs at much lower temperatures than combustion. Furthermore, this study determines global oxidation rates at 400-600�C for three important products of fast pyrolysis: levoglucosan, xylose, and acetic acid. Experiments were performed in a fluidized bed pyrolyzer with the reactor modeled as a series of CSTRs and PFRs to determine reaction rates. Oxidation rates at 500�C for the three model compounds varied by a factor of ten.
