Two grades of recycled wood (Waste Wood A and Waste Wood B) were fractionated on a pilot scale (800 BD kg) to monomeric sugars, lignin and lignosulfonates using SO₂-Ethanol-Water (AVAP®) technology including pretreatment, separation of cellulosic and hemicellulosic streams, and saccharification. Carbohydrate mass balance was obtained through determination of poly-, oligo- and monosaccharides as well as sugar degradation products in process streams. High monosaccharide yields were obtained confirming laboratory scale findings. Fermentability of mixed cellulosic and hemicellulosic sugar stream was confirmed on bench scale (25 kg).

再生木材中试规模的二氧化硫-乙醇-水分馏成糖，生物乙醇，木质素和木质素磺酸盐：碳水化合物平衡

使用SO _2-乙醇-水（AVAP®）技术（包括预处理，纤维素分离）将中档两级回收木材（废木A和废木B）以中试规模（800 BD kg）分级为单体糖，木质素和木质素磺酸盐。以及半纤维素流和糖化作用。通过测定工艺流中的多糖，寡糖和单糖以及糖降解产物，获得了碳水化合物的质量平衡。获得了高单糖产量，证实了实验室规模的发现。实验室规模（25公斤）证实了纤维素和半纤维素混合糖流的发酵能力。
