Optimization of Lignofiber (LGF) organosolv process for fractionation of lignocellulosics

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific

Abstract

The aim of this work was to optimize the LGF organosolv process using acetic acid as the solvent, by attempting to enhance the xylan recovery and to increase the dissolution of lignin during the process. In addition, the goal was to make the process more suitable for industrial purposes, by shortening the cooking time. Xylan recovery prior to LGF organosolv pulping was achieved by performing an alkaline extraction at elevated temperature and with high alkali concentration and low liquid to wood ratio. Lignin removal from the LGF pulps was greatly improved by enhanced washing of the pulps and significant reduction in cooking time can be obtained
