“…So far, only one gas-phase process has been established by Davy McKee Ltd. [6] which consists of two stages. A potential problem in gas-phase operation comprises fouling and plugging of the fixed-bed by polymeric material [7,8]. The polymeric deposits (polyesters) can be formed upon trans-esterification of dialkyl esters of maleic or succinic acid with the product BDO.…”

Bifunctional catalysts consisting of copper, zinc oxide, and γ -alumina have been produced by means of extrusion. The effects of formulation and forming conditions on morphology, pore texture, and copper surface area are discussed. These extruded catalysts have been employed in the fixed-bed gas-phase conversion of dimethyl maleate at temperatures between 453 and 493 K and space velocities ranging from 0.2 to 2.4 h −1 . Copper catalyzes the hydrogenation and hydrogenolysis reactions yielding γ -butyrolactone, and 1,4-butanediol. γ -Alumina provides weakly acidic sites which promote the subsequent dehydration of 1,4-butanediol to tetrahydrofuran. Coupled products are methanol and water. Through choice of composition and pore texture of the extrudates it is possible to achieve tetrahydrofuran yields of 100% (basis the C 4 -products) at a low pressure (2.5 MPa) in a single stage.

“…[301,339,340] Moreover, anew route was described for the formation of THF through the hydrogenation of maleic acid, which can in turn be synthesized from bio-derived platform chemicals such as aspartic acid. [277,341] 2-Methyltetrahydrofuran (2-MTHF) 2-MTHF (boiling point = 80.20 8 8C; density = 0.854 gcm À3 ) is ac olorless liquid with al imited miscibility with water (14 wt %a t2 0 8 8C), which shows ar emarkable stability to hydrolysis or polymerization compared to the unsubstituted THF. [342] Moreover,i fa ccidentally spilled from ar eaction container into the surrounding environment, 2-MTHF can be abiotically degraded by sunlight and air,presumably through oxidation and ring opening.…”

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.

“…The production of THF from succinic acid was investigated in a number of studies [86][87][88][89]. A process for the continuous production of THF was presented by Kanetaka et al [86], through the direct maleic anhydride hydrogenation to succinic acid, which is further hydrogenated to THF.…”

“…A process for the continuous production of THF was presented by Kanetaka et al [86], through the direct maleic anhydride hydrogenation to succinic acid, which is further hydrogenated to THF. The study shows that the process provided a high selectivity to THF, up to 90%, and full conversion of maleic anhydride per-pass.…”

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.
