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
