Dissolving Pulp (alpha-cellulose) from Corn Stalk by Kraft Process
Corn stalk can be used as an alternative non-wood raw material to produce cellulosic dissolving grade pulp. In this work, the potential of corn stalk in the production of dissolving pulp (alpha-cellulose) was investigated. It was collect ed from a corn stalk farm of Kermanshah, Iran. The sequences of experimental work were: water and acid prehydrolysis at 160˚C for 30min, followed by Kraft pulp...
متن کاملSolvent extraction of antioxidants from steam exploded sugarcane bagasse and enzymatic convertibility of the solid fraction.
Solvent extraction of steam exploded lignocellulosic biomass may be a potential way to obtain antioxidative extracts and to enhance the enzymatic convertibility of the solid residue. Boiling solvent extraction (BSE) showed higher solid and phenolic yields than room temperature extraction. Solubilities of phenolics and sugars were higher in anhydrous ethanol (AE) and deionized water (DW) than in...
متن کاملThermal Degradation Kinetics of Sugarcane Bagasse and Soft Wood Cellulose
The properties of untreated sugar cane bagasse (SCB) and soft wood (SW) and their respective celluloses were investigated. The celluloses indicated improved crystallinity index values and decreased concentration of lignin and hemicellulose compared to their untreated counterparts. Three degradation models, Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (OFW), and Kissinger (KGR) methods were ...
متن کاملMethane Potential and Enzymatic Saccharification of Steam-exploded Bagasse
To evaluate the biofuel potential of bagasse, an abundant co-product in sugarcane-based industries, the effect of steam explosion on the efficiency of enzymatic saccharification and anaerobic digestion was studied. Bagasse was steam exploded at four different severity levels, and the impact of pretreatment was evaluated by analyzing the release of glucose after enzymatic saccharification with C...
متن کاملThermal analysis of cellulose esters prepared from different molecular weight fractions of high α-cellulose pulp
High α-cellulose has been dissolved in two non-degrading solvent systems like dimethyl sulfoxide/paraformaldehyde (DMSO/PF) and N,N-dimethyl acetamide/lithium chloride (DMAc/LiCl) and then fractionated to different molecular weight fractions by regeneration technique. Esters of the different molecular weight fractions of cellulose have been prepared having substitution chain length of C2-C5 usi...
