Structural Variation of Bamboo Lignin before and after Ethanol Organosolv Pretreatment
In order to make better use of lignocellulosic biomass for the production of renewable fuels and chemicals, it is necessary to disrupt its recalcitrant structure through pretreatment. Specifically, organosolv pretreatment is a feasible method. The main advantage of this method compared to other lignocellulosic pretreatment technologies is the extraction of high-quality lignin for the production...
متن کاملEthanol Organosolv Pretreatment of Bamboo for Efficient Enzymatic Saccharification
Bamboo is a potential lignocellulosic biomass for the production of bioethanol because of its high cellulose and hemicelluloses content. In this research, ethanol organosolv pretreatment with dilute sulfuric acid as the catalyst was studied in order to enhance enzymatic saccharification of moso bamboo. The addition of 2% (w/w bamboo) dilute sulfuric acid in 75% ethanol had a particularly strong...
متن کاملAnatomy, Cell Wall Ultrastructure and Inhomogeneity in Lignin Distribution of Broussonetia Papyrifera
Broussonetia papyrifera (Linn.) Vent has been attracting interest recently as a valuable wood source for pulping and papermaking manufacturing. The present study aims to determine the anatomical structure, ultrastructure and distribution of lignin in the fiber cell walls of this shrub, using electron microscopy, fluorescence microscopy (FM) and confocal Raman microscopy, which, to our knowledge...
متن کاملLow-Power Microwave Radiation-assisted Depolymerization of Ethanol Organosolv Lignin in Ethanol/Formic Acid Mixtures
Ethanol organosolv lignin separated from bamboo was depolymerized by low-power microwave radiation (~80 W) using ethanol as a swelling agent and formic acid as a hydrogen donor solvent. After increasing the temperature from 100 to 200 °C, the total amount of phenolic compounds in the products increased from 8.1% to 40.8%, and both the weight average molecular weight (Mw) and number average mole...
متن کاملEffects of Extraction Conditions on the Characteristics of Ethanol Organosolv Lignin from Bamboo (Phyllostachys pubescens Mazel)
The structure and properties of ethanol organosolv lignin (EOL) extracted from bamboo under various conditions were characterized. EOL yield increased at high temperatures of 160 to 200 °C and a reaction time of 1 to 3 h. The nitrogen content in lignin was low, with a maximum of 0.62%. The carbon content increased with increasing temperature and prolonged time, whereas oxygen content showed an ...
