Abstract:
Co-torrefaction (CT) was performed on rice husk, coffee bean ground and their various blending ratio such as CBG:RH (25:75%), CBG:RH (50:50%), CBG:RH (75:25%), CBG 100%, and RH 100% as well as the impact of temperature were studied. The co-torrefaction experiments were performed using a laboratory scale tube furnace varying temperature from 200 °C- 300 °C. Reduction in mass and energy yields was because of increased temperature. At (75:25%) biomass concentration the volatile matter dropped to 8.03% while carbon content raised 12.9%. Also, the oxygen-to-carbon reduced 34.45% with increased temperature. The FTIR spectrum which confirmed release of the functional group of the volatile components such as H2O, CO and CO2 etc. In addition, the torrefaction index on a yield basis (weight loss, performance index, and torrefaction index) is increased at temperature of 300 °C. The high carbon content and better fuel properties were found for CBG 100% and blending ratio of CBG:RH (75:25%) at 300 °C for 60 min as a bio-solid production of 65.2%. This research found that co-torrefaction improves CBG, RH, and their blends as bio-solid fuel for energy applications.
