    "description": "<p>In this study, beechwood was fractionated in lab-scale rector by one-stage and two-stage processes. The two-stage processes of the prehydrolysis with no catalyst (only water) and catalyst (sulfuric, phosphoric, oxalic acids), and the subsequent effect on the organosolv process were studied. A one-stage organosolv delignification of beech wood (control experiment) was conducted at 155 &ordm;C for 160 min in 1:1 ethanol/water mixture with 100 mM sulfuric acid, while the two-stage processes were conducted starting from the uncatalyzed and catalyzed (20-200 mM) prehydrolysis of beech wood at 175 &ordm;C for 60 min. The results indicate that sulfuric acid enhanced the removal of xylan from beechwood during the prehydrolysis stage. Moreover, the effectiveness of the delignification of beech wood using a one-stage process is more than the two-stage, as well as the enzymatic digestibility of the pulp, which was better than those of the two-stage processes. However, the enzymatic digestibility results of the pulp obtained after sulfuric acid-catalyzed prehydrolysis followed by organosolv delignification shown better results than the other two-stage processes. Additionally, high klason content, low sugar content, low M<sub>w</sub>, and high phenolic hydroxyl groups of lignin was recovered by a one-stage organosolv delignification.</p>",
