Abstract

This work investigates the kinetics of fast pyrolysis of different biomasses using thermogravimetric analysis and DWSIM software. The rising energy demands are one of the main reasons responsible for a sudden change in global temperature and environmental pollution. In this regard, biomass energy systems provide considerable opportunities to replace the energy system which are dependent on fossil fuels. Biomass through thermal conversion has great scope in producing important items, that can be utilized as a feedstock for various chemical production and can simply be used as a fuel. Pyrolysis is known to be a process that is utilized since ages to change biomass into either bio-oil or bio-char. Biofuels are considerable due to diverse grounds such as their role in entrap** carbon, and stocks of energy. The efficiency of mathematical models, which can be used to forecast the properties of biomass, depends on the precise specification of the feedstock and their thermal decay. TGA has resulted to be a methodology that can specify the properties of biomass promptly and systematically. The average range of temperature for the procedure is 30–900 °C. To create an inert atmosphere nitrogen was being used. In this study, the activation energy of the thermal degradation for the different samples of biomasses was evaluated by the Arrhenius equation and then compared with Coats–Redfern equation. Biomass pyrolysis is a promising route for the conversion of waste biomass into useful product that is bio-oil. The present work investigates the fast pyrolysis of different biomasses. Kinetic knowledge is of great importance in achieving good control of the pyrolysis process and in optimizing system design. The present work creates a kinetic pyrolysis scheme based on the TGA analysis of few biomass samples.
