Abstract
Abstract This paper deals with the pyrolysis of forest waste in the presence of an inert atmosphere. Experiments are carried out at different heating rates (5 °C, 10 °C and 15 °C) to determine derivative thermogravimetric behaviour of the material. Unlike the conventional scheme, the Monte Carlo technique is implemented to solve the distributed activation energy model (DAEM). DAEM is transformed into the inverse pyrolysis problem to determine the kinetic parameters of thermal degradation of forest waste. Activation energy, the preexponential factor and the distribution parameters are estimated by introducing the Monte Carlo Technique in the thermal conversion process.
Highlights
Modelling scheme of biomass pyrolysis can be performed on the basis of single reaction and multi-reaction models
It is assumed that the significant behaviour of total integrand (Equation (1) and (2)) is about the central value (Es) of temperature integral, it reflects the activation energy required to initiate the thermal decomposition of the pine waste
It is indicated that the energy required during the dehydration phase of pine needles vary from 25 kJ/mol to 50 kJ/mol, whereas the activation energy rises steadily until the char formation
Summary
Modelling scheme of biomass pyrolysis can be performed on the basis of single reaction and multi-reaction models. Comprehensive details of these models are reviewed in previous research [1]–[4]. As the trade-off relationship between material decomposition and mathematical model is fail to impart the robustness in the results, the Monte Carlo scheme is adopted to make the solution more pragmatic. Some of the latest developments and the effect of various parameters on the single-reaction model are investigated by Brown [8]. Dhaundiyal et al [10], [11] performed a comprehensive analysis of various density functions to predict the nature of thermal decomposition of biomass through DAEM
