Influence of Temperature on the Elemental, Combustion and Energy Properties of Carbonized Water Hyacinth Biomass

Short Introductive summary

This study reports the valorization of water hyacinth biomass feedstock via the carbonization/ slow pyrolysis route and examines the influence of carbonizing temperatures of 350, 450 and 550 °C at a heating rate of 10°C/min for 2 h on its performance. WHB waste causes serious resource waste and environmental pollution. Hence, the preparation of char from WHB via carbonisation is of great significance. The pyrolysis process involves carbonizing the WHB feedstock biomass to study the effect of a process parameter in an oxygen-free environment to produce charcoal as the main product along with low molecular liquids and gases [1]. The elemental composition of the char was investigated under the ultimate analysis, the evolution of functional groups in the char under different temperatures were analyzed by the FTIR and HHV of the WHB char samples obtained via the Bomb calorimetry experiment. Results shows increase in temperature, decrease in mass yield of the char and increase in HHV of the char. Content of the char increased up to 40.4% at CWH 550 with a corresponding HHV value of 27.1 MJ/kg at time of 120 min. Results shows that carbonisation route can facilitate the transformation
