Hemicellulose can be extracted from loblolly pine by dilute acid hydrolysis, and the remaining wood mass can be delignified to produce cellulose fiber. This paper contains an assessment of the technical and economic feasibility of co-producing ethanol and bleached cellulose fiber from loblolly pine, for a mill producing 1398 ODT/day of unbleached fiber. Ethanol is produced by extracting between 6% and 18% of the dry wood mass prior to pulping. The extracted wood mass, which contains about 70… CONTINUE READING
