Abstract
Pretreatment of lignocellulosic biomass, break down of lignin structure and destroy the crystalline structure, is first important step to produce valuable materials. A well-known hydrolysis method with concentrated mineral acids has a drawback that the abundance of salts is formed by the following neutralization step. In this study, we investigated the effective pretreatment process from lignosellulosic biomass to holocellulose by treating the wet pulverization biomass with decreased oxidative reagents. In addition, we developed the selective hydrolysis method from holocellulose to xylose by using Amberlite IR-120H as a solid acid catalyst. This reaction can be achieved under mild conditions without producing large amounts of solid waste.
