“…DMF's advantages over ethanol, which include a higher energy density and insolubility in water [15], have promoted its awareness as a promising gasoline-alternative fuel. Until recently, the research about DMF has focused on its production methods and fundamental combustion characteristics [15][16][17][18][19][20][21][22][23]. The authors of this paper recently reported the engine combustion and emissions characteristics of DMF [24].…”

A silicon carbide microtubular reactor has been used to measure branching ratios in the thermal decomposition of furan, C4H4O. The pyrolysis experiments are carried out by passing a dilute mixture of furan (roughly 0.01 %) entrained in a stream of helium through the heated reactor. The SiC reactor (0.6 mm i.d, 2 mm o.d., 2.5 cm long) operates with continuous flow. Experiments were performed with a reactor inlet pressure of 100-300 Torr and a "chemical temperature" within the reactor of approximately 1100-1400 K; characteristic residence times in the reactor are 100-200 µsec. Tunable synchrotron radiation photoionization mass spectrometry is used to monitor the products, measure the branching ratio of the two carbenes as well as the ratio of [HCCCH2]/[HC≡CCH3]. The results of our experiments clearly demonstrate a preference for the decomposition channel through a β-carbene. At temperatures of 1100-1200 K, only HC≡CCH3 is produced. As the temperature rises to 1300-1400 K, roughly 10 % of the flux through the β-carbene channel goes to HCCCH2 radicals.

“…Pure 2,5-DMF has also been the focus of numerous flame characterization studies [212][213][214][215][216][217][218]. One of the earliest efforts with regards to flame investigation is the study by Wu et al [212], where a premixed laminar 2,5-DMF/O 2 /Ar flame at a pressure of 4 kPa and an equivalence ratio of 2.0 was investigated with tunable synchrotron VUV photoionization coupled with molecular-beam mass spectrometry.…”

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.
