摘要 |
<p>A process of treating a lignocellulosic material includes a pre-extraction step in which hemicellulose is extracted from the lignocellulosic material. Then, in a solvent pulping step, the lignocellulosic material is separated into pulp by contacting the lignocellulosic material with a cooking liquor comprising a solvent.
