“…There are two possible pathways for the hydrogenation of LA proposed in Scheme 2 [39,40]. It is often proposed that the first step during the hydrogenation reaction was a conception of molecular hydrogen and liquid LA on the metal support [39,[65][66][67][68][69][70]. Hydrogen following the division of the H diatom, was adsorbed on the surface of Ru to form the bond between Ru and hydrogen, and then LA were adsorbed on the surface of Ru by the combination of Ru with carbonylic C and O atoms.…”

“…Cu and Ni-based catalysts) have become an important research target where the implementation of LDH-derived catalysts is attracting enormous attention in both batch and continuous reaction processes. Yan et al 142,143 reported the utilization of Cu-catalysts derived from hydrotalcite precursors as highly selective catalysts for the hydrogenation of levulinic acid to obtain GVL in aqueous phase. Among the different Cu-catalysts studied (Cu-Al, Cu-Cr, Cu-Fe) Cu-Cr hydrotalcite showed the highest selectivity, achieving 100% conversion and 91% yield towards GVL after 10 h reaction (T = 200°C, 70 bar of H 2 pressure), whereas the worst catalyst was Cu-Fe hydrotalcite.…”

Recent advances on the utilization of layered double hydroxides (LDHs) and related heterogeneous catalysts in a lignocellulosic-feedstock biorefinery scheme

Layered double hydroxides (LDHs) and derived materials have been widely used as heterogeneous catalysts for different types of reactions either in gas or in liquid phase. Among these processes, the valorization/upgrading of lignocellulosic biomass and derived molecules have attracted enormous attention because it constitutes a pivotal axis in the transition from an economic model based on fossil resources to one based on renewable biomass resources with preference for biomass waste streams. Proof of this is the increasing amount of literature reports regarding the rational design and implementation of LDHs and related materials in catalytic processes such as: depolymerization, hydrogenation, selective oxidations, and C-C coupling reactions, among others, where biomass-derived compounds are used. The major aim of this contribution is to situate the most recent advances on the implementation of these types of catalysts into a lignocellulosic-feedstock biorefinery scheme, highlighting the versatility of LDHs and derived materials as multifunctional, tunable, cheap and easy to produce heterogeneous catalysts.

“…A similar yield was achieved by Yan et al [99], who used a noble-free Cu-Fe catalyst for the hydrogenation of levulinic acid, achieving a 2-MTHF yield of 3.5%. Even lower yields of 2-MTHF were achieved using Cu-based Fe-free catalysts [47].…”

Abstract:There is growing interest in the use of furans, a class of alternative fuels derived from biomass, as transportation fuels. This paper reviews recent progress in the characterization of its combustion properties. It reviews their production processes, theoretical kinetic explorations and fundamental combustion properties. The theoretical efforts are focused on the mechanistic pathways for furan decomposition and oxidation, as well as the development of detailed chemical kinetic models. The experiments reviewed are mostly concerned with the temporal evolutions of homogeneous reactors and the propagation of laminar flames. The main thrust in homogeneous reactors is to determine global chemical time scales such as ignition delay times. Some studies have adopted a comparative approach to bring out reactivity differences. Chemical kinetic models with varying degrees of predictive success have been established. Experiments have revealed the relative behavior of their combustion. The growing body of literature in this area of combustion chemistry of alternative fuels shows a great potential for these fuels in terms of sustainable production and engine performance. However, these studies raise further questions regarding the chemical interactions of furans with other hydrocarbons. There are also open questions about the toxicity of the byproducts of combustion.
