Wet torrefaction pre-treatment of yard waste to improve the fuel properties

The utilization of biomass has emerged as an attainable alternative for energy production. However, the intrinsic properties of biomass including hygroscopic behaviour, heterogeneity in structure and high moisture content constraint the usage of biomass in bioenergy applications. Wet torrefaction en...
