摘要：
Pre-extraction of hemicelluloses prior to pulping and conversion of the extracted hemicelluloses to other by-products will provide additional revenues to the traditional pulp and paper industry. The effects of hemicelluloses pre-extraction with dilute sulfuric acid on the properties of aspen chemi-thermomechanical pulp (CTMP) were investigated. The acid pre-extraction significantly reduced refining energy consumption to a given freeness. However, at the same freeness, the acid pre-extraction resulted in the reduction of bulk and tensile index, fewer long fibers and more fines, but increase of Scott bond. Alkaline peroxide bleaching can compensate the strength loss, but the brightness of pulps with acid pre-extraction was still lower than that of the control.
