PULPING PROCESS FOR QUALITY PROTECTION INCLUDING METHODS FOR HEMICELLULOSE EXTRACTION AND TREATMENT OF HEMICELLULOSE -EXTRACTED LIGNOCELLULOSIC MATERIALS |
摘要 |
<p>A method for producing pulp by extracting hemicellulosic materials from lignocellulosic materials using water in an extraction stage, wherein the extraction stage is either a single extraction or a double extraction process; treating the lignocellulosic materials with an oxidizing agent in a treatment stage, wherein the treatment stage is selected from the group consisting of a second extraction process, an agent impregnation process, and a first pretreatment process; treating the lignocellulosic materials with a reducing agent in the treatment stage, wherein the treatment stage is selected from the group consisting of the second extraction process, the agent impregnation process, and a second pretreatment process; and then subjecting the lignocellulosic materials to a modified Kraft pulping process to produce pulp.</p> |
