Abstract
This article describes methods of the determination of kinetic parameters from the thermogravimetric data set of biomass samples. It presents the methodology of the research, description of the needed equipment, and the method of analysis of thermogravimetric data. It describes both methodology of obtaining quantitative data such as kinetic parameters as well as of obtaining qualitative data like the composition of biomass. The study is focused mainly on plant biomass because it is easy in harvesting and preparation. Methodology is shown on the sample containing corn stover which is subsequently pyrolysed. The investigated sample show the kinetic of first order reaction. Basing on the analysis of thermogravimetric graphs it is concluded that nearly half of the sample comprises cellulose, the second in order of weight component is hemicellulose, and the third is xylan. Rest of components do not exceed 10% of the sample mass. For the determination of kinetic parameters the Coats-Redfern method is used. The calculated kinetic parameters might be useful in design of torrefaction, gasification and pyrolysis reactors.
