Investigation into torrefaction kinetics of biomass and combustion behaviors of raw, torrefied and char samples

Thermal decomposition of sugarcane bagasse (SCB), yellow poplar (YP), and biomass polymers (xylan, cellulose and lignin) were studied under isothermal conditions using a specially designed thermogravimetric analyzer (Quartz Wool Matrix, QWM) in the temperature range 240–300 °C. Reactivity of biomass was predicted using the measured reactivity of three individual polymers and a simple arithmetic superposition principle. The superposition model...
