Upgrading Biomass By Torrefaction (2)
The disadvantage of the combustion process is in smoke produced. This is because the moisture content of biomass is relatively high comparing to other solid fuels such as coal. It influences to ignite in combustion reactor. Another disadvantage of biomass is that the hygroscopic ability. If biomass is stored for a couple of days, the quality will decrease. Researcher shows that the torrefaction is a path to treat biomass before transportation or thermochemical conversion.
