Abstract

Steam explosion and rapid steam hydrolysis/continuous extraction (RASH) processes were compared using sweetgum and white oak as the feedstocks. Both pretreatments employ steam and are relatively rapid, but there are several differences between the two processes. Both pretreatments dramatically increased the enzymatic hydrolysis rate but not the acid hydrolysis rate of the cellulose. Both water insoluble xylose or alkali insoluble lignin contents could be used to predict the relative enzymatic hydrolysis rate. Steam explosion depolymerized and degraded the hemicelluloses, whereas RASH minimized further degradation of the hemicelluloses. The lignin was depolymerized by both pretreatments, with steam explosion forming a moderately condensed lignin. No significant differences were observed between white oak and sweetgum samples treated by either process, suggesting that the selection of particular hardwood is not a critical factor for a potential biomass plant in the southeastern US.
