“…An interesting one-step approach for the synthesis of 2-MTHF from pentose sugars was presented by Yang and Sen [109,110]. The process used a soluble rhodium catalyst, hydrogen and Hl/HCl+Nal for the deoxygenation of xylose towards the formation of 2-MTHF.…”

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.

“…By hydrogenation, HMF can be converted into 2,5-dimethyl-furan (DMF) and 2,5-dimethyl-tetrahydrofuran (DMTHF), which possess both a high octane number and high energy content to replace gasoline directly [75][76][77][78][79][80][81]. Dumesic et al developed a CuRu/C catalyst that could in situ hydrogenate HMF produced in a water/1-butanol biphasic system into DMF [76].…”

“…The neat HMF can be converted into DMF using most of the precious metal catalysts such as Pd, Pt, Ru, and Rh supported on active carbon [79]. In the case of HMF conversion to DMTHF, RhCl 3 in aqueous solution can be used as catalyst to in situ hydrogenate HMF from fructose dehydration into DMTHF with more than 80 % DMTHF yield achieved [81].…”

Biomass has the potential to serve as a sustainable source of energy and organic carbon for our industrial society. The focus of this chapter is to provide a survey of different strategies to achieve chemical catalytic conversion of biomass-derived oxygenated feedstocks to value-added chemicals and fuels. The key reactions involved in the processing of biomass are hydrolysis, dehydration, isomerization, aldol condensation, reforming, hydrogenation/hydrogenolysis, and oxidation. Here, a few specific examples, namely efficient hydrolysis of cellulose over novel solid acids and synthesis of polyols by hydrogenation/hydrogenolysis of cellulose and sugar have been chosen for this review. Further, the selective conversion of platform molecules, such as furan, HMF, and biogenic carboxylic acids into intermediates, specialties, and fine chemicals has been considered. While many challenges are involved in biomass processing, understanding of fundamental reaction chemistry for different types of reactions can lead to the development of new approaches for specific processes.

“…With the enhanced demand for fuel, gradually decreased reserves of fossil fuel and increased climate concerns about its utilization, much attention has been focused on the conversion of biomass into bio-oil by pyrolysis or liquefaction due to its characteristics of sustainability and carbon-neutral renewability [1][2][3]. However, this bio-oil contains many kinds of oxygen-containing compounds including phenols, aldehydes and ketones, and its composition changes with the pyrolysis or liquefaction conditions and the type of feedstock [4,5].…”

This study prepared unsupported MoS 2 catalysts by a one-step hydrothermal method using ammonium heptamolybdate and thiocarbamide as materials. The morphology and microstructure of MoS 2 catalysts were changed by adding different amounts of hexadecyl trimethyl ammonium bromide (CTAB). The resultant catalysts were characterized by X-ray diffraction, nitrogen physisorption and transmission electron microscopy. The surface area and pore volume of MoS 2 increased first and then decreased with the addition amount of CTAB. The structural difference between these catalysts lies in the number of layers in stacks and slab length of MoS 2 structure. The structure-activity correlation was studied by using the hydrodeoxygenation (HDO) of p-cresol as the probe reaction. In the HDO of p-cresol, the end products were toluene, 4-methylcyclohexene and methylcyclohexane, and the possible HDO reaction routes were proposed. The effects of addition of CTAB during the synthesis of MoS 2 and HDO reaction temperature on conversion and products distribution were analyzed. The changes of product distribution were explained based on the Rim-Edge model. The direct deoxygenation (DDO) route occurs on the edge active sites while the hydrogenation-dehydration (HYD) route occurs on brim sites of multistacks MoS 2 particles. Thus, the slab length and slab stacking layers had a great effect on the catalytic activity of MoS 2 and products distribution.Electronic supplementary material The online version of this article (
