摘要

Biomass is one of the most promising renewable energy sources due to its worldwide availability, the possibility of producing heat and power on demand, and its potential CO₂ neutrality. However, there is a lack of characterization of residual biomasses from agro-industrial processes. This study presents a comprehensive characterization and kinetic modeling of Lippia origanoides bagasse, a residual biomass from essential oil extraction. The proximate analysis revealed moisture contents of 9.47% (leaves), 9.26% (stems), and 9.89% (mixture), with volatile matter reaching up to 75.67% in stems and ash content as low as 5.50%, indicating favorable combustion properties. The estimated higher heating value (HHV) of the stem fraction was 18.65 MJ/kg, which is 6.7% higher than the leaves fraction and 1.9% higher than the mixture. Elemental composition showed carbon contents of 46.43% (stems), 43.77% (leaves), and 45.64% (mixture), supporting its energy potential. Kinetic parameters were determined using the independent parallel reaction scheme (IPRS), with activation energies ranging from 61.3 to 256.7 kJ/mol depending on the biomass type and atmosphere. This approach represents a significant advancement over previous single-step kinetic models applied to this biomass. Modeled decomposition curves showed excellent agreement with experimental data (%Fit < 5%). These findings highlight the potential of Lippia origanoides bagasse—particularly its stem fraction—as a viable solid fuel and provide ro bust parameters for simulating its thermal behavior.
