Abstract The production of cellulosic ethanol from biomass is considered a promising alternative to reliance on diminishing supplies fossil fuels, providing sustainable option for fuels in an environmentally compatible manner. conversion lignocellulosic biofuels through biological route usually suffers the intrinsic recalcitrance owing complicated structure plant cell walls. Currently, pretreatment step that can effectively reduce generally required make polysaccharide fractions locked...
Abstract This study examined the application of select ionic liquids (ILs) as aprotic green solvents for lignin. Dissolution experiments were carried out employing lignin isolated from pine kraft pulp. Up to 20 wt% could be dissolved in [hmim][CF3SO3], [mmim][MeSO4] and [bmim][MeSO4]. For [bmim]+‐containing liquids, order solubility varying anions was: [MeSO4]−>Cl−∼Br−⋙[PF6]−, indicating that was principally influenced by nature anions. Ionic containing large, non‐coordinating [PF4]− [PF6]−...
The last decade has seen tremendous growth and interest in renewable energy fuels aimed primarily at addressing issues of climate change, security, rising costs. These efforts coupled with the demand for efficient utilization biomass place a premium on detailed analysis fundamental chemical structures biomass, especially light ever-increasing to generate transgenic plants reduced recalcitrance altered lignin structure. This review examines growing application phosphitylation followed by 31P...
With rapidly increased interests in biomass, diverse chemical and biological processes have been applied for biomass utilization. Fourier transform infrared (FTIR) analysis has used characterizing different types of their products, including natural processed biomass. During treatments, some solvents and/or catalysts can be retained contaminate In addition, contaminants generated by the decomposition components. Herein, we report FTIR analyses a series contaminants, such as various solvents,...
ABSTRACT In dilute acid pretreatment of lignocellulosic biomass, lignin has been shown to form droplets that deposit on the cellulose surface and retard enzymatic digestion (Donohoe et al., 2008; Selig 2007). However, studies this nature are limited for hydrothermal pretreatment, with result corresponding mechanisms inhibit cellulosic enzymes not well understood. study, scanning electron microscope (SEM) wet chemical analysis solids formed by a mixture Avicel poplar wood showed from...
Abstract A new method to prepare nanolignin using a simple high shear homogenizer is presented. The kraft lignin particles with broad distribution ranging from large micron‐ nano‐sized were completely homogenized sizes less than 100 nm after 4 h of mechanical shearing. 13 C nuclear magnetic resonance (NMR) and 31 P NMR analysis showed that there no major changes in the chemical composition between starting obtained treatment. did not show any change molecular weight polydispersity compared...
3D printing by fused deposition modeling (FDM) is an advanced additive manufacturing technology for making thermoplastic-based structures. Several studies have recently investigated of polylactic acid (PLA) with biomass resources like cellulose, hemicellulose, lignin and whole biomass. Such biodegradable composites are better the environment can be used to replace non-biodegradable in a variety applications. Therefore, deep understanding such biocomposites needed supporting manufacturing....
The utilization of lignin for fungible fuels and chemicals represents one the most imminent challenges in modern biorefineries.
Abstract Society's increasing demand for transportation fuels has assured a viable future the development of renewable fuels. Although first‐generation biofuels are dependent on starches, sugars and vegetable oils, need to generate higher volumes at lower cost shifted research focus cellulosic ethanol. The utilization lignocellulosics sustainable manufacturing is critically chemical constituents starting biomass desired fuel properties. This review examines major recent advances in their...
Effects of organosolv and ammonia pretreatments were understood by investigating the changes lignin properties its inhibition for enzymatic hydrolysis using diverse analysis methods.
In this study, Populus trichocarpa was subjected to dilute acid pretreatment at varying times. The three major components of lignocellulosic biomass, namely cellulose, hemicellulose and lignin, were isolated from the starting pretreated poplar. Gel permeation chromatography (GPC) nuclear magnetic resonance (NMR) techniques utilized elucidate structural transformations poplar during pretreatment. results demonstrated that dissolved hemicelluloses disrupted features lignin polysaccharides. As...
Lignin is the second most abundant biopolymer on earth, yet its utilization for fungible products complicated by recalcitrant nature and remains a major challenge sustainable lignocellulosic biorefineries.
