Biomass processing wastes (humins) are anticipated to become a large-tonnage solid waste in the near future, owing to the accelerated development of renewable technologies based on utilization of carbohydrates. In this work, the utility of humins as a feedstock for the production of activated carbon by various methods (pyrolysis, physical and chemical activation, or combined approaches) was evaluated. The obtained activated carbons were tested as potential electrode materials for supercapacitor applications and demonstrated combined micro- and mesoporous structures with a good capacitance of 370 F g (at a current density of 0.5 A g ) and good cycling stability with a capacitance retention of 92 % after 10 000 charge/discharge cycles (at 10 A g in 6 m aqueous KOH electrolyte). The applicability of the developed activated carbon for practical usage as a supercapacitor electrode material was demonstrated by its successful utilization in symmetric two-electrode cells and by powering electric devices. These findings provide a new approach to deal with the problem of sustainable wastes utilization and to advance challenging energy storage applications.

“…[85] This is also reflected in al arge number of reports dedicated to the catalytic conversion of carbohydrates into HMF by using typical acidic resins, functionalized silica, zeolites, heteropolyacids, and other solids. [86][87][88] Notwithstanding the ability to recover heterogeneous catalysts by filtration, homogeneous catalysts can often be efficiently recovered by the simple removal of the organic phase, which containsp roducts, [84,89] leaving the acid catalyst in the aqueous phase. On the other hand, solid acids are frequently disposedofdue to their irreversible deactivation by the formation of byproduct polymer humins on their surface.…”

Acid‐Catalyzed Conversion of Carbohydrates into Value‐Added Small Molecules in Aqueous Media and Ionic Liquids

2018

View full text Add to dashboard Cite

Biomass is the only realistic major alternative source (to crude oil) of hydrocarbon substrates for the commercial synthesis of bulk and fine chemicals. Within biomass, terrestrial sources are the most accessible, and therein lignocellulosic materials are most abundant. Although lignin shows promise for the delivery of certain types of organic molecules, cellulose is a biopolymer with significant potential for conversion into high-volume and high-value chemicals. This review covers the acid-catalyzed conversion of lower value (poly)carbohydrates into valorized organic building-block chemicals (platform molecules). It focuses on those conversions performed in aqueous media or ionic liquids to provide the reader with a perspective on what can be considered a best case scenario, that is, that the overall process is as sustainable as possible.

Development of sustainable bio‐based materials for removal of toxic contaminants from water is a high priority goal. Novel bio‐based binary and ternary copolymers with enhanced ion‐exchange, adsorption and antibacterial properties were obtained by using plant biomass‐derived diallyl esters of furandicarboxylic acid (FDCA) as crosslinking agents and easily available vinyl monomers. The synthesized copolymer materials showed higher sorption capacities for NiII, CoII and CuII compared to the commercial ion‐exchange resins, and they maintained their high metal adsorption capacities for over 10 cycles of regeneration. The synthesized copolymer gels containing 1–5 wt % of the crosslinker showed excellent water absorption capacities. The synthesized copolymers with 1 % crosslinker content showed swelling ratios high enough to also act as moisture absorbents. Synthesized copolymers with crosslinker content of 10 wt % performed as contact‐active antibacterials by inhibiting the growth of Gram‐positive (S. aureus) and Gram‐negative bacteria (E. coli, K. pneumonia) in suspension tests.
