Fig. 1From: Flowthrough pretreatment with very dilute acid provides insights into high lignin contribution to biomass recalcitranceComposition and solid yields. Composition of poplar prior to pretreatment and yields and compositions of solids produced by liquid hot water (LHW) and extremely dilute acid (EDA) batch and flowthrough pretreatments. Number labels have been rounded-off to the nearest whole number for clarity. The components other than glucan, xylan, and total lignin labeled “Others” were not measured experimentallyBack to article page
