Investigation of kinetic triplets and thermodynamic parameters of different species of bamboo-biomass from North-East India

Abstract

Bamboo is abundantly available in India, particularly in the North East regions which can provide a significant energy opportunity in this region. The physicochemical and thermal properties of bamboo species originate from different places are distinct. This study investigates the pyrolysis of 20 different bamboo species from North East regions of India in a thermogravimetric analyser (TGA) at four different heating rates of 10, 20, 30, and 40 K/min. Enormous kinetic and thermodynamic data are presented for 20 varieties of bamboo species. Model-free kinetic methods are used to calculate the kinetic parameters and their values are compared. The average activation energy of all bamboo species is estimated in the range 145.59–219.15 kJ/mol from the Starink method, the method recommended by International Confederation of Thermal Analysis and Calorimetry (ICTAC). Generalized master plot method is used for the determination of reaction mechanism which reveals that most of the bamboo species follow the second-order reaction model (F2) during their thermal degradation. The thermodynamic parameters reveal that the pyrolysis process of all bamboo species is endothermic and it reaches near to the thermodynamic equilibrium.
