473500 Thermochemical Characterization of Sugarcane Bagasse for the Production of Combustibles Via Pyrolysis Using N2 As Carrier Gas
Global warming is a large-scale issue that has led humanity to seek for renewable energy sources. Biomass thermal gasification is one the new technologies to produce clean fuels using biomass as feedstock. The resultant product from this process is a renewable neutral carbon fuel. Temperature parametric results obtained from a sugarcane-bagasse (CH1.581O0.671N0.00306S0.00117) pyrolysis experimental study carried out at pyrolysis temperatures ranging between 400⁰C and 900⁰C and at a heating rate of 4.30⁰C/min ± 7.8%, are discussed. The experiments were developed in a static batch reactor with nitrogen as carrier gas. Sugarcane bagasse samples were thermo-chemically characterized in order to determine thermodynamic properties such as enthalpy of formation, high heating value, empirical formulas of biomass, volatile matter, etc. The chemical formula of the pyrolysis oil obtained was estimated using gas composition, given by a gas analyzer, and atom balance on components. The effect of temperature on the production of liquid and gaseous fuels are presented along with the HHV of the syngas produced. The following results were obtained: chemical empirical formulas for biomass and volatile matter were CH1.581O0.671N0.00306S0.00117 and CH1.807O0.767N0.00349S0.00133 respectively; high heating values (DAF basis) of biomass and volatile matter 18,925.08 kJ/kg and 17,472.77 kJ/kg, respectively; average chemical empirical formula of liquid fuel CH1.942O0.484N0.005S0.002.
