“…14) by using heterogeneous or homogeneous catalytic systems. 141 However, the development of noble metal-free heterogeneous catalysts for this reaction (e.g. 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.…”

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.

“…An attractive option regarding the one-pot synthesis of levulinate esters via performing the reaction of furfuryl alcohol with alcohols can be envisioned because the reforming process is atom-economic and convenient, the alcohols suppress humin by-product formation from furfuryl alcohol polymerization [7], and it affords versatile platform chemicals. Concretely, levulinate esters have found applications as fuels or fuel additives [8,9], flavoring agents, solvents, as well as in the area of organic chemistry for the synthesis of γ-valerolactone [10,11], liquid hydrocarbon transportation fuels [12], and other industrial chemicals [13].…”

Abstract:Levulinate ester has been identified as a promising renewable fuel additive and platform chemical. Here, the use of a wide range of common metal salts as acid catalysts for catalytic upgrading of biomass-derived furfuryl alcohol to butyl levulinate was explored by conventional heating. Both alkali and alkaline earth metal chlorides did not lead effectively to the conversion of furfuryl alcohol, while several transition metal chlorides (CrCl 3 , FeCl 3 , and CuCl 2 ) and AlCl 3 exhibited catalytic activity for the synthesis of butyl levulinate. For their sulfates (Cr(III), Fe(III), Cu(II), and Al(III)), the catalytic activity was low. The reaction performance was correlated with the Brønsted acidity of the reaction system derived from the hydrolysis/alcoholysis of cations, but was more dependent on the Lewis acidity from the metal salts. Among these investigated metal salts, CuCl 2 was found to be uniquely effective, leading to the conversion of furfuryl alcohol to butyl levulinate with an optimized yield of 95%. Moreover, CuCl 2 could be recovered efficiently from the resulting reaction mixture and remained with almost unchanged catalytic activity in multiple recycling runs.

“…Its energy density is 24.6 MJ/L, which is slightly higher than that of ethanol (23.5 MJ/L), but lower than gasoline (31.2 MJ/L) and diesel (33.6 MJ/L) [10,12]. Furthermore, alkyl levulinates found applications as flavoring agents [13], solvents [14], as well as in the area of organic chemistry for the synthesis of c-valerolactone [15,16], liquid hydrocarbon transportation fuels [17] and other industrial chemicals [9].…”
