Liquid biofuels produced from cellulosic biomass can significantly reduce the nation's dependence on foreign oil, create new jobs, improve rural economies, reduce greenhouse gas emissions, and improve national security. Moreover, cellulosic biomass would not bring a competition for farmland with food and feed products. Nevertheless, significant hurdles must be overcome to cost-effectively manufacture cellulosic biofuels. One of the hurdles is related to the low density of cellulosic feedstocks, which causes high costs in their transportation and storage. Pelleting can increase the density of cellulosic feedstocks; therefore, can increase the overall efficiency by utilizing existing transportation infrastructure and storage systems. This paper presents an experimental study on ultrasonic vibration assisted (UV-A) pelleting of switchgrass. This study focuses on the effects of binder material. The results show that, in UV-A pelleting, the influence of the binder material on pellet density, stability, and durability is not significant. If UV-A pelleting can produce pellets without adding binder materials, the pelleting cost will be reduced.
