The Effect of Fermentation (Retting) Time and Harvest Time on Kudzu , Fiber Strengthated for possible economic applications. The feasibility of removing the fibers by microbial retting is investigated as a low-cost method for recovery of these fibers. The harvest season, vine diameter, and the natural retting time are the three main variables investigated to determine the optimal f

Optimization of Reverse-Flow, Two-Temperature, Dilute-Acid Pretreatment to Enhance Biomass Conversioimulate countercurrent flow of the biomass solids and prehydrolysis liquor, and to exploit the xylan biphasic kinetics. Lower temperatures (150-174°C) are initially applied to hydrolyze the easily hydrolyzable xylan, and higher temperatures (180–204°C) are applied to hydrolyze the remaining xylan. T

Sorptive Recovery of Dilute Ethanol from Distillation Column Bottoms Streamize substantial str ipping steam to achieve this result. An alternate approach using sorption was attempted as a means to reduce energy requirements in the stripping section, and thereby reduce cost. Adsorbents tested for use in such an application showed that carbonaceous supports, in particular Am

Measurement of the Inhibitory Potential and Detoxification of Biomass Pretreatment Hydrolysate for Ehe relative toxicity of a variety of hydrolysate samples derived from dilute-acid and alkaline biomass pretreatment. Toxicity is elicited from biomass degradation products, such as furfural, hydroxymethyl furfural, and acetic acid, generated during pretreatment. Microtox results indicate that the pr

Ethanolic Fermentation of Lignocellulose Hydrolysatesuction of liquid fuels, such as ethanol. Using transportation fuels from renewable resources should not contribute to global warming, generally referred to as the “greenhouse effect,” and would thus assure sustainable development of the transportation sector. This argument is based on the assumption
