Sugarcane Bagasse Torrefaction for Fluidized Bed Gasification

Sugarcane bagasse has a great potential to be used as biofuel; however, its use feedstock in fluidized bed reactors is hampered due fibrous nature, low apparent density, high moisture content, and difficulties with fluidization. The present study evaluated the torrefaction of sugarcane propose suitable process conditions that balance properties fuel obtained process’s energy requirements. Based on thermogravimetric analysis previous reports, two final temperatures (230 °C 280 °C) residence times (35 45 min) for same heating rate (5 °C/min) nitrogen flow (1 L/min) were evaluated. Within experimental evaluated, it can concluded 30 min time, average target temperature 230 should enough produce stable torrefacted 3.41% reduction volatile content obtain 98.85% yield. Higher increase feedstock’s carbon but yield fraction volatiles do not justify higher or longer pretreating bagasse.
