Effective degradation of cellulose by Microwave irradiation in alkaline solution

نویسندگان

چکیده

Lignocellulose biomass effectively produces chemicals and fuels, which are of importance for the establishment a sustainable society. The conversion cellulose, main component biomass, into significant precursors that can be further converted to different or fuels under gentle conditions is promising route. Organic acids such as acetic, glycolic formic acid examples. A novel method produce important platform from micro-crystalline cellulose (MCC) was developed. MCC degraded result oxidation with potassium chlorate by microwave radiation in one-pot procedure. Efficient reaction short time full were identified. products analyzed 1H 13C NMR, XPS, TGA XRD.

X-ray irradiation induced degradation of cellulose nitrate

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry was previously proposed to measure the thickness of the cellulose nitrate layer of he commonly used LR 115 solid-state nuclear track detector (SSNTD). The present work is devoted to the investigation whether the X-ray radiation nvolved in EDXRF spectrometry will induce degradation of the cellulose nitrate. For this purpose, Fourier trans...

Preparation of carboxymethyl chitosan in aqueous solution under microwave irradiation.

Carboxymethyl chitosan was prepared by reacting chitosan with chloroacetic acid in water under microwave irradiation. The effect of the reaction conditions was investigated and optimal conditions were identified. The influence of mass ratio of chloroacetic acid to chitosan, microwave power and pH on the degree of substitution or intrinsic viscosity were further studied. The degree of substituti...

Cellulose degradation by oxidative enzymes

Enzymatic degradation of plant biomass has attracted intensive research interest for the production of economically viable biofuels. Here we present an overview of the recent findings on biocatalysts implicated in the oxidative cleavage of cellulose, including polysaccharide monooxygenases (PMOs or LPMOs which stands for lytic PMOs), cellobiose dehydrogenases (CDHs) and members of carbohydrate-...

Enhancement of Cellulose Degradation by Cattle Saliva

Saccharification of cellulose is a promising technique for producing alternative source of energy. However, the efficiency of conversion of cellulose into soluble sugar using any currently available methodology is too low for industrial application. Many additives, such as surfactants, have been shown to enhance the efficiency of cellulose-to-sugar conversion. In this study, we have examined fi...
