During the combustion of switchgrass sulfur dioxide is released. Therefore, the objective of the present study is to evaluate the kinetics of formation of sulphur dioxide during switchgrass combustion. Experimental data obtained by the National Renewable Energy Institute in Colorado was used to evaluate the kinetic data. Conversion of switchgrass was described by the Discrete Particle Method (DPM) that is an efficient tool to predict all major processes such as heating-up, pyrolysis and combustion. In conjunction with initial and boundary conditions and a given set of kinetic parameters allows for prediction of the sulphur dioxide emission. The rate of sulphur dioxide formation is approximated by an Arrhenius-like ex- pression. These parameters were determined by a least square method so that the deviation between the measured data and predictions was minimized. The kinetic data determined yielded good agreement between experimental data and predictions. [less ▲]
