“…Alkylation using conventional zeolites, layered 2D and 3D acidic zeolites has been explored as a useful reaction for either improving the H/C ratio in bio-oils, 409 producing biofuels 410 or for the production of high value chemicals, such as xylenes, ethylbenzene and ethyltoluene. 411 Large pore zeolites are more convenient than small and medium pore size ones due to lower mass transfer restrictions.…”

Research activities and recent developments in the area of three-dimensional zeolites and their two-dimensional analogues are reviewed. Zeolites are the most important industrial heterogeneous catalysts with numerous applications. However, they suffer from limited pore sizes not allowing penetration of sterically demanding molecules to their channel systems and to active sites. We briefly highlight here the synthesis, properties and catalytic potential of three-dimensional zeolites followed by a discussion of hierarchical zeolites combining micro- and mesoporosity. The final part is devoted to two-dimensional analogues developed recently. Novel bottom-up and top-down synthetic approaches for two-dimensional zeolites, their properties, and catalytic performances are thoroughly discussed in this review.

“…5‐Hydroxymethylfurfural (HMF), obtained by dehydration of hexoses, constitutes one of the most important and versatile platform molecules, owing to its broad range of potential applications in the biofuels and chemical industries. Numerous transformations of HMF, such as, oxidation, reduction, etherification, alkylation, aldol condensation, acetalization, hydration, and reductive amination, have been reported in recent years . Among them, the reduction of the formyl group of HMF to afford the symmetrical diol 2,5‐bis(hydroxymethyl)furan (BHMF), has received much attention .…”

Biobased plasticizers, as substitutes for phthalates, have been synthesized from 5‐hydroxymethylfurfural (HMF) and carboxylic acids (or esters) through a chemoenzymatic cascade process that involves as its first step the reduction of 5‐hydroxymethylfurfural into 2,5‐bis(hydroxymethyl)furan (BHMF), followed by the esterification of BHMF with carboxylic acids (or esters) by using a supported lipase (Novozym 435). The reduction of HMF into BHMF is performed by using monodisperse metallic Co nanoparticles with a thin carbon shell (Co@C) with high activity and selectivity. After optimization of reaction conditions (temperature, hydrogen pressure, and solvent), it is possible to achieve 97 % conversion of HMF with 99 % selectivity to BHMF after 2 h reaction time. The reduction of HMF and esterification of BHMF using carboxylic acids or vinyl esters as acyl donors by lipase are optimized separately in batch and in fixed‐bed continuous reactors. The coupling of two flow reactors (for reduction and subsequent esterification) working under optimized reaction conditions affords the diesters of BHMF in roughly 90 % yield with no loss of activity during 60 h of operation.

“…High carbon furylmethanes with branched chain backbone are first synthesized by C-C coupling of furans with carbonyl functional groups [19] , which are then hydrodeoxygenated (HDO) to alkanes [5] . C-C coupling reactions over acid or base catalysts have been reported, e.g., hydroxyalkylation/alkylation (HAA) [12][13][14][15][16][17][18][19][20][21][22][23] , aldol condensation [24][25] , alkylation [26] , benzoic condensation [27][28] , giving high yields [47] .…”

Catalytic Hydrodeoxygenation of High Carbon Furylmethanes to Renewable Jet‐fuel Ranged Alkanes over a Rhenium‐Modified Iridium Catalyst

et al. 2017

Renewable jet-fuel-range alkanes are synthesized by hydrodeoxygenation of lignocellulose-derived high-carbon furylmethanes over ReO -modified Ir/SiO catalysts under mild reaction conditions. Ir-ReO /SiO with a Re/Ir molar ratio of 2:1 exhibits the best performance, achieving a combined alkanes yield of 82-99 % from C -C furylmethanes. The catalyst can be regenerated in three consecutive cycles with only about 12 % loss in the combined alkanes yield. Mechanistically, the furan moieties of furylmethanes undergo simultaneous ring saturation and ring opening to form a mixture of complex oxygenates consisting of saturated furan rings, mono-keto groups, and mono-hydroxy groups. Then, these oxygenates undergo a cascade of hydrogenolysis reactions to alkanes. The high activity of Ir-ReO /SiO arises from a synergy between Ir and ReO , whereby the acidic sites of partially reduced ReO activate the C-O bonds of the saturated furans and alcoholic groups while the Ir sites are responsible for hydrogenation with H .
