摘要：

Present study focused on the thermo-chemical potential of waste biomass of Eichhornia crassipes or water hyacinth root (WHR). The pyrolysis-kinetic parameters are investigated using thermo-gravimetric analysis at the various heating rates (5, 10, 15, and 20 degrees C/min). Three model-free techniques, Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), and Starink, were used for the thermal kinetic analysis of biomass. The average activation energy for WHR biomass was determined using KAS, FWO, and Starink, with the values of 57.87, 64.69, and 58.27 kJ/mol, respectively. From the study it is observed that the roots of water hyacinth have rich in carbon, oxygen and hydrogen composition around 24%, 70% and 4% respectively. The higher heating value of water hyacinth root was observed around 15 MJ/kg.
