Abstract: This disclosure relates to methods of making novel dissolving wood pulps by processes comprising acid prehydrolysis, pulping, and a multi-stage bleaching process comprising oxidation with a catalyst and peroxide under acidic conditions, as well as to products made therefrom having a combination of medium-purity, low viscosity, and improved reactivity, filterability, and/or clogging that can be used as a substitute for traditional high-purity dissolving pulps in a wide variety of applications.

Abstract: Processes are disclosed for extracting sugar rich liquor from sugar cane. The sugar cane is first treated by pulping it in two tub type pulpers having a rotating impeller. The contents of the first pulper are extracted through the bedplate of the extractor and are forwarded onto the second pulper. The contents of the second pulper are extracted through the bedplate of the extractor and are forwarded to form a mat on a moving belt countercurrent extractor of the type having a foraminous belt. Negative pressure is applied below the belt to assist the extraction of a sugar rich liquid component through the belt. The material passes through several separation zones as it travels on the belt with liquid applied to the mat from a region above the belt. The extracted liquid component is collected for further processing.
