“…It can be directly derived from biomass sources and can be further converted to useful chemicals and fuels via hydrogenation and hydrodeoxygenation (HDO). In this context, a model reaction that has received significant attention is the hydrogenation of furfural to furfuryl alcohol [1][2][3][4][5][6][7][8]. In spite of a substantial amount of study, however, furfural hydrogenation catalysts, most of which are based on transition metals or metal alloys, are still incompletely understood, and the hydrogenation process remains the subject of a significant amount research [2,7,[9][10][11].…”

“…Conversely, reaction steps such as aldehyde hydrogenation (AH) and hydrodeoxygenation (HDO) necessary for conversion of furfuryl oxygenates to desirable fuels (furfuryl alcohol and methylfuran) do not occur as readily. [3][4][5][6][7][8] Figure 1 depicts the major reaction pathways for furfural hydrogenation.…”

One key route for controlling reaction selectivity in heterogeneous catalysis is to prepare catalysts that exhibit only specific types of sites required for desired product formation. Here we show that alkanethiolate self-assembled monolayers with varying surface densities can be used to tune selectivity to desired hydrogenation and hydrodeoxygenation products during the reaction of furfural on supported palladium catalysts. Vibrational spectroscopic studies demonstrate that the selectivity improvement is achieved by controlling the availability of specific sites for the hydrogenation of furfural on supported palladium catalysts through the selection of an appropriate alkanethiolate. Increasing self-assembled monolayer density by controlling the steric bulk of the organic tail ligand restricts adsorption on terrace sites and dramatically increases selectivity to desired products furfuryl alcohol and methylfuran. This technique of active-site selection simultaneously serves both to enhance selectivity and provide insight into the reaction mechanism.

“…In a study by Zhang et al [96], the catalytic performance of K-doped Pd/Al 2 O 3 catalysts was investigated during the decarbonylation of furfural to THF over a temperature range of 453-533 K and atmospheric pressure. The results revealed that doping the Pd-K/Al 2 O 3 catalyst doped with K 2 CO 3 with an 8 wt % K-loading achieved total furfural conversion and a maximum THF and furan yields in the decarbonylation reaction.…”

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.
