Determination of kinetic parameters for Finnish milled peat using drop tube reactor and optical measurement techniques

The present paper deals with the pyrolysis of Finnish milled peat with different residence times in the laboratory-scale drop tube reactor. Based on the experimental results, the kinetic parameters for Finnish milled peat are determined and some important properties of the reactor and peat are identified using optical measurement techniques. Furthermore, it is demonstrated that in drop tube reactors the drag coefficient of the fuel particle might be a major source of error.
