Furfural from corn stover hemicelluloses. A mineral acid-free approach

Abstract: Furfural was obtained from corn stover hemicelluloses by a\ud microwave-assisted, green and heterogeneously catalyzed twostep cascade process as follows: first step, hydrothermal fractionation of corn stover hemicelluloses, and second step, hydrolysis/dehydration of soluble hemicellulosic sugars over niobium phosphate\ud to yield furfural at moderate temperatures (<200 °C), with\ud both steps being performed in water. Furfural yields of up to 23 mol% with respect to the starting raw biomass were reached

“…The further dehydration of pentoses generates furfural, a potential chemical platform for the synthesis of several chemicals and biofuels [10,11]. Furfural can also be produced directly from cascade hydrolysis and dehydration of hemicellulose; in this respect, solid acid catalysts are typically used in biphasic solvent systems in order to promote the process [12,13]. The use of solid acid catalysts has been recently studied in the conversion of furfural into high-added value products ( Figure 1) [14,15].…”

“…1 Recent investigations have also identified furfural as a viable plant-derived biochemical alternative to petrochemicals, as a part of sustainable bio-refineries aimed at reducing pollution. [2][3][4][5] With no direct synthetic methods of production, 1 furfural is solely produced through the thermochemical pre-treatment of biomass. While it is desirable to increase the conversion efficiency of hemicellulose into furfural, from the view point of furfural as a commodity chemical, 1 its production within some bio-refineries is undesirable, as it can inhibit enzymes responsible for upconversion of pre-treated biomass.…”

“…In Figs. 2-5 we present our Bands I and II SMCPP-SEP results, for the cases of 4,6,7,31,53,57, and 63 open electronic channels in our MOB-SCI framework and in each case for the incident electrons arriving as plane waves and exiting as spherical waves up to L max = 13. Born-closure is applied throughout.…”

“…In our recent investigations into the quantum chemical structure and electronic-state spectroscopy of furfural, 1 its ionisation dynamics 2 and its vibrational spectroscopy, 3 we made the case for furfural being identified as a key platform chemical 4,5 in the commercial realisation of bio-refineries. 6 We therefore do not repeat the detail of those arguments here, rather we reiterate briefly the following rationale.…”
