Biomass storage conditions are a major source of feedstock quality variability that impact downstream preprocessing, feeding, handling and conversion into biofuels, chems. and products. Microbial activity in the stored biomass can result in heating that can modify or degrade the cell walls of the biomass, changing its characteristics. Anal. pyrolysis has been used to characterize biomass, but at temperatures typically used (∼600°C), differentiation of samples having different storage histories is subtle or non-existent. In this study, lower-temperature (400°C) pyrolysis was used to show large differences in corn stover samples that had experienced different biol. heating histories, indicated by pyrolysis products that were identified, and in several cases quantified using two-dimensional gas chromatog. / mass spectrometry. Pyrolysis of the samples originating from biomass that had experienced biol. heating during storage generated small oxygenates such as furfural, 5-Me furfural and 2-(5H)-furanone with efficiencies that were as much as ten times greater than those measured for samples that were not significantly heated. Most of the pyrolysis products with enhanced efficiencies were C5 oxygenates, suggesting formation from hemicellulosic precursor polymers in the corn stover. The findings suggest that biol. heating is disrupting the cell wall structure, fragmenting the hemicellulose or cellulose chains, and generating more polymer termini that have higher efficiency for generating the oxygenates at lower temperatures Further, anal. pyrolysis conducted at lower temperatures may be a beneficial strategy for improved biomass cell wall characterization, and for providing insights to understand and manage the feedstock variability to inform harvest and storage best management practices. The experimental part of the paper was very detailed, including the reaction process of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Recommanded Product: 3-Hydroxydihydrofuran-2(3H)-one)
3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9) is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde. And it may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis.Recommanded Product: 3-Hydroxydihydrofuran-2(3H)-one
