Hydrolysis of Cellulose and Hemicellulose
Cellulosic biomass includes agricultural (e.g., corn stover and sugarcane bagasse) and forestry (e.g., sawdust, thinnings, andmill wastes) residues, portions ofmunicipal solid waste (e.g., waste paper), and herbaceous (e.g., switchgrass) and woody (e.g., poplar trees) crops. Such materials are abundant and competitive in price with petroleum, and cellulosic biomass can provide a sustainable res...
متن کاملCellulose–Hemicellulose and Cellulose–Lignin Interactions during Fast Pyrolysis
Previously, the primary product distribution resulting from fast pyrolysis of cellulose, hemicellulose, and lignin was quantified. This study extends the analysis to the examinations of interactions between cellulose−hemicellulose and cellulose−lignin, which were determined by comparing the pyrolysis products from their native mixture, physical mixture, and superposition of individual component...
متن کاملElectric Properties of Carboxymethyl Cellulose
Carboxymethyl cellulose [C6H7O(OH)3x(OCH2COOH)x]n is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxy ethanoic acid) CH2(OH)COOH or sodium monochloroacetate ClCH2COONa. The CMC backbone consist of D-glucose residues linked by -1,4-linkage. The molecular mass of one glucose unit in CMC chain is mCMC = 146.14 + 75.04x, where x 3 is the degree of substitu...
متن کاملChromatography of ribonuclease on carboxymethyl cellulose columns.
In the course of an investigation of the chemical phosphorylation of ribonucleasel (cf. (l)), it became necessary to develop a chromatographic procedure for the fractionation of the phosphorylated protein. The method of Hirs et al. (2), employing the weak cation exchanger Amberlite XE-64, is an extremely valuable method for the chromatographic purification of pancreatic ribonuclease, but the us...
متن کاملStudy of the Physicochemical and Rheological Behaviors of Hybrid Oleogels Based on Monoacylglycerol and Carboxymethyl Cellulose
Background and Objectives: Due to the hydrophilic nature of cellulose derivatives which are widely used in food industries, special methods should be used to dissolve these compounds in oil. In this study, carboxymethylcellulose (CMC) was used to increase strength of monoacylglycerol (MAGs) gels. In the present study, simultaneous effects of MAG and CMC on the production of hybrid oleogels were...
