Abstract
⺠Ethanol prod via alkaline pretreatment enables a coproduction of valuable lignin. ⺠Lignin content of 2.5% on pulp was found optimum for aspen and 5% on pulp for pine. ⺠Aspen required lower alkali charge and lower temperature compared to pine. ⺠Yield gain of fermentable sugars is 1-2% charging AQ(0.1% on wood) in pretreatment. ⺠Ethanol yield between 81.6% and 87.8% on theoretical max was obtained.
