Abstract

Five different chemical pretreatments, using dilute sulfuric acid, sodium hydroxide, hydrogen peroxide and sodium hydroxide, peroxy- monosulfate, and acetic acid, were applied to aspen thermomechanical fibers. The pretreated fibers were submitted to enzymatic hydrolysis and the liberated glucose was monitored. High glucose concentra- tions were observed for the peroxymonosulfate and the acetic acid pretreated samples. Glucose concentrations greater than 25 g/L were obtained in these cases. This corresponds to conversions on the order of 90% of the pretreated substrate glucose content.
