Abstract

Graphical abstract: Highlights: Kinetic study of phoenix dactylifera seeds and Aegle Marmelos L through TGA. Kinetic study using Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose and Starink. Activation energy analysed using Starink model in case of PDS is ∼ 170.71 kJ/mol. Maximum activation energy using Starink model for AMP is found to be ∼ 164.80 kJ/mol. PDS and AMP can be potential for biofuels production through thermo-chemical route. Abstract: The present study explores thermo-chemical potential of two biomasses namely; Phoenix dactylifera seed (PDS) and Aegle marmelos L core (AMP). These biomasses contain high amount of cellulose and exhibit heating value of 3–18 MJ/kg. The thermal kinetic of both the biomasses have been extensively studied using thermogravimetric analysis (TGA) at four different heating rates 5, 10, 15, and 20 °C/min. Kinetic analysis was carried out using three model-free techniques including Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and Starink. The average activation energy has been found to be 173.75, 172.94 and 170.71 kJ/mol, for PDS whereas 170.26, 167.24 and 164.80 kJ/mol, for AMP analyzed through KAS, FWO and Starink methods, respectively. Further, among all these models, the Starink model exhibits better result for the biofuels potential point of view.
