Alkali Extraction of Hemicellulose from Depithed Corn Stover and Effects on Soda-aq Pulping
A biorefinery using the process of hemicellulose pre-extraction and subsequent pulping provides a promising way for the utilization of straw biomass and resolution of problems related to silicon. In this work, hemicellulose was extracted from depithed corn stover with sodium hydroxide solution before soda-AQ pulping. Components of the extracts were quantified by ion chromatography. The paramete...
متن کاملinvestigation on soda and soda- aq pulping of whole kenaf
the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...
متن کاملThe Effect of Hot-Water Pre-Extraction on the Properties of Soda-AQ Pulp of Wheat Straw
This research investigated the effect of hot water pre-extraction on the bleaching process and properties of wheat straw soda-AQ pulp. Preextraction experiments were carried out on wheat straw to obtain a weight loss of about 15 percent. Based on preliminary experiments, soda-AQ pulping of non-extracted straw chips was performed at 160 oC for 60 min, whereas the pre-extracted chips were pulped ...
متن کاملMultifunctional Alkaline Pulping, Delignification and Hemicellulose Extraction
In this study, multifunctional alkaline pulping was suggested to produce different pulp grades at one mill site, ranging from high-yield paper pulp to high-purity dissolving pulp. In all process modifications, sulfur was successfully replaced by anthraquinone. Autohydrolysis and alkaline pre-extraction were applied to Eucalyptus globulus wood chips, followed by kraft and soda-AQ pulping. Alkali...
متن کاملPartial flow of compressed-hot water through corn stover to enhance hemicellulose sugar recovery and enzymatic digestibility of cellulose.
Flowthrough pretreatment with compressed-hot water can significantly increase the removal of xylan and lignin and enhance xylose sugar yields and cellulose digestibility, especially at high flow rates. However, continuous flowthrough operations that realize these benefits suffer from a large amount of water consumption that leads to high energy requirements for pretreatment and downstream proce...
