Feasibility of Pelletization and torrefaction of agricultural and woody biomass

Authors: GHIASI, B., S. SOKHANSANJ, C. JIM LIM
Description: Torrefied biomass represents a high quality renewable energy commodity that can be used to substitute fossil fuels such as coal. However, densification processes such as pelletisation is necessary to improve the tradability of “low-dense” torrefied biomass. The problem with torrefied biomass is difficulty of densifying the materials and production of durable and dense pellets. Especially pelletization of torrefied biomass is much problematic for agricultural biomass. This research investigates steam treatment of biomass to produce dense and durable pellets. Softwood chips (Pine and Douglas-fir) and agricultural biomass (Switch grass, wheat straw and corn stover) were pelletised and torrefied. Moisture content of the raw material prior to pelletization and the materials residence time in the pellet press were key role factors affecting density and durability of pellets both for woody and agricultural pellets. No binder was needed when biomas was steam treated.
