Sorptive Recovery of Dilute Ethanol from Distillation Column Bottoms Stream used. These experimentally determined operating conditions combined with distillation energy calculations have enabled development of a process concept for sorptive concentration of dilute ethanol which is more energy efficient than distillation alone. The combination of existing distillation and c

Kinetic and Modeling Investigationon on Two-Stage Reverse-Flow Reactoras Applied to Dilute-Acid Pretand two-stage reverse-flow operation, was modeled and investigated for its performance. The modeling results affirmed that a step-change/reverse-flow operation is advantageous for biphasic substrates, including agricultural residues. The optimum temperature difference in the step-change operation wa

Fractionation of Herbaceous Biomass by Ammonia-Hydrogen Peroxide Percolation TreatmentThe remaining solids had a composition of 80–93% glucan, 5–10% xylan, and 1–6% lignin. Selected solid samples. obtained under near-optimum conditions, exhibited a chemical composition close to that of commercial a-cellulose The enzymatic digestibilities of these solid samples were substantially high
