Peroxyalkanoic cellulose purification of steam exploded yellow poplar
Water and alkali extracted steam exploded yellow poplar fiber (log R₀ 4.25) was purified through a multi-stage process. The initial stage consisted of peralkanoic acid treatment, either formic or acetic acid, at atmospheric pressure. Subsequent bleaching was achieved through treatment with alkaline …

Clean Fractionation of Biomass - Steam Explosion and Extraction
… terms of relative cleanness. Red oak chips were steam exploded using a batch reactor at five different treatment severities, Ro 5,000, 10,000, 15,000, 20,000 and 35,000. Steam exploded fibers (SEF) of each severity were extracted with water and alkali. Mass fractionation and summative analysis …

Optimization of the production of bioethanol from duckweed (Lemna minor)
… additional use of thermophysical pretreatment (steam explosion) results in a dramatic decrease in the amount of enzyme required for quantitative saccharification. A more advanced commercial cellulase cocktail (Cellic® CTec 2; CTec 2) is likely to further reduce the enzyme cost. Methods for the …

Cellulose fiber reinforced thermoplastic composites: Processing and Product Charateristics
Steam exploded fibers from Yellow Poplar (Liriodendron tulipifera) wood were assessed in terms of (a) their impact on torque during melt processing of a thermoplastic cellulose ester (plasticized CAB); (b) their fiber incorporation and dispersion characteristics in a CAB-based composite by SEM and …

Steam Explosion Pretreatment of Cotton Gin Waste for Fuel Ethanol Production
… This study focused on the use of steam explosion as the pretreatment method. Steam explosion treatment of biomass has been previously described to increase cellulose accessibility. The governing factors for the effectiveness of steam explosion are steam temperature and retention …

Bioconversion of lignocellulosic hydrolysate to acetic acid using Moorella thermoacetica
… Four different hydrolysates obtained after steam pretreatment of lignocellulosic biomass were selected and fermented to acetic acid in batch fermentations. The bacterial strain (ATCC 39073) can effectively ferment xylose and glucose in steam exploded hydrolysates from wheat straw, forest …
