Global Gas-Phase Oxidation Rates of Select Products from the Fast Pyrolysis of Lignocellulose

The oxidation kinetics for products of fast pyrolysis at low temperatures (<600 °C) are not well-known. These will be important in an effort to model autothermal pyrolysis, which has been recently developed intensify the process but occurs much lower than combustion. This study determines global rates 400–600 °C three pyrolysis: levoglucosan, xylose, and acetic acid. Experiments were performed a fluidized bed pyrolyzer with reactor modeled as series continuously stirred reactors plug flow determine reaction rates. Oxidation 500 compounds varied by factor 10.
