“…The combustion processes of these complex, oxygen-containing species are of current interest 6,7 and have only recently been subjected to engine studies. 8,9,10 We use a heated microtubular (µtubular) reactor as a device to study the pyrolysis of these new oxygenated fuels. The µtubular reactor 11 operates at a nominal pressure of 100 Torr and at temperatures up to about 1600 K. The goal of this paper is to describe the nature of the pyrolysis of furan, the parent compound in eq.…”

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.

Sustainably produced biofuels, especially when they are derived from lignocellulosic biomass, are being discussed intensively for future ground transportation. Traditionally, research activities focus on the synthesis process, while leaving their combustion properties to be evaluated by a different community. This Review adopts an integrative view of engine combustion and fuel synthesis, focusing on chemical aspects as the common denominator. It will be demonstrated that a fundamental understanding of the combustion process can be instrumental to derive design criteria for the molecular structure of fuel candidates, which can then be targets for the analysis of synthetic pathways and the development of catalytic production routes. With such an integrative approach to fuel design, it will be possible to improve systematically the entire system, spanning biomass feedstock, conversion process, fuel, engine, and pollutants with a view to improve the carbon footprint, increase efficiency, and reduce emissions.

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.
