摘要
The Organosolv pulping is a process to separate lignocellulosic biomass into its components cellulose, hemicellulose and lignin. Usually this process is catalyzed by Bronsted acids. In this work the Bronsted acid is replaced by the Lewis acid aluminum chloride. Much less aluminum chloride is needed to achieve similar pulp properties like high cellulose recovery, high hemicellulose and lignin removal. Also aluminum chloride catalyzes the degradation of xylose to the important basic chemicals furfural and lactic acid.
