Abstract
Introduction
This paper describes a process for the separation and recovery of non-structural phenolic compounds from switchgrass. This process is proposed as a preliminary step of a biorefinery incorporating the organosolv process for biomass fractionation. The economics of such an addition to separate and recover phenolic compounds is then investigated.
Switchgrass has been selected as a dedicated feedstock for bioprocesses producing liquid fuels such as ethanol and advanced fuels. The University of Tennessee has been heavily involved in the development of switchgrass as one of the feedstocks for bioenergy production in the southeast (Tiller 2011). Biofuels have the potential to address problems related to fossil fuels such as carbon emissions, as long as they are produced sustainably while reducing risks to food security, wildlife, land, water, and air resources. Switchgrass can be grown on underutilized or marginal land where there is no or minimal competition with land that is used for food crop production. In addition, switchgrass does not require irrigation due to its inherent drought tolerance, and is a low input crop for producing bioenergy from farmland. With an extensive root system, switchgrass provides significant positive environmental benefits, prevents erosion, improves soil structure, and sequesters carbon in the soils.
