| Abstract/Summary |
As a representative of biomass, in particular the sewage sludge, the raw bacterial cellulose was chosen. The thermogravimetric analysis (TGA) was employed in the investigation of thermal processing of the biomass. The experiments were carried out in the temperature range 30—1000ºC. Di erent values of heating rate from 2.5 to 20 K min−1 were applied. In order to determine kinetics of thermal decomposition of the biomass derivative of TG curve (DTG) was deconvoluted, using Gauss pro le, into few fractions (lumps), each of which was represented by a single rst-order reaction. The rst-order kinetic parameters such as activation energy Ei and pre-exponential factor Ai were estimated. The high values of activation energy indicated the chemical reaction regime of thermal processing of the biomass.
