Method for removing stickies from secondary fibers using supercritical CO2 solvent extraction |
摘要 |
A process for removing sticky contaminants ("stickies") from cellulose-containing fibers such as waste paper is provided. The process comprises contacting the fibers with supercritical or near supercritical carbon dioxide for a period of time sufficient to extract a substantial portion of the stickies without substantially damaging the fibers.
