Herein, we studied the effects of pretreatment with glucanase (G), xylanase (X), and their combinations [G/X mixtures or sequential addition (G–X and X–G)] on the efficiency of ionic liquid/water (IL/w)—promoted extraction of hemicelluloses from paper-grade pulp. Mild G pretreatment effectively increased the efficiency and selectivity of hemicellulose removal, whereas severe G pretreatment resulted...
Herein, an ionic liquid/water (IL/w) system was developed to separate hemicelluloses from the chemical pulp with enhanced efficiency by employing xylanase. In the traditional IL/w process, when the water content was in the range 20-15%, the extraction of hemicelluloses was 71–80%. However, the highly efficient hemicelluloses removal was always accompanied with an increased cellulose loss. In this...
