Abstract

Thermal kinetics of Sal seeds during pyrolysis process was investigated as feedstocks for chemical, material, and bioenergy industries. The physicochemical properties of the seeds were examined. Results showed that Sal seed can be characterized as high calorific values, low ash, and high volatile content biomass to suit pyrolysis applications. Kinetic analysis for thermal degradation of this biomass was given particular attention. Two major degradation zones were identified with T max at about 321 and 405 °C, and activation energy was evaluated using various methods. Model-free pyrolysis kinetic approach was verified to be appropriate and indicated that unprocessed Sal seed biomass can directly become potential renewable feedstock of energy, chemicals, and biochar.
