“…For MeFo, there are only a few uses in the fuel sector. A patent of MeFo as an additive to gasoline by Klezl 21 was the only application-oriented reference to MeFo as a fuel a few years ago until Ha¨rtl et al 22,23 investigated the potential of a fuel mixture of MeFo and DMC. In addition to reducing the exhaust emission, MeFo as well as DMC have a high octane number that could improve the combustion process.…”

In the future, synthetic fuels could replace fossil fuels to minimize the CO2 emissions of combustion engines. Dimethyl carbonate (DMC) and methyl formate (MeFo) represent not only possible synthetic fuels but, due to their oxygen content, also have properties to reduce the pollutant emissions. For a good combustion process, the spray targeting and evaporation properties are important. Due to the less known injection behavior of DMC and MeFo, the spray characteristics were examined in a pressure chamber. The penetration depth, projected spray area, and spray angle were investigated at injection pressures of 100 and 200 bar, chamber pressures of 1 and 2.5 bar, and a temperature variation of up to 90°C for two different injector spray angles and flow rates in comparison with gasoline E5. The spray was recorded with a high-speed camera in a constant-volume chamber with a N2 environment. Both fuels showed a faster evaporation than E5 even with a higher injection mass due to their lower LHV. MeFo showed extreme spray collapse and flash boiling effects, which lead to even faster evaporation rates and higher penetration velocities.

Oxymethylene dimethyl ethers (OMEn; CH3(‐OCH2)n‐OCH3) are promising sustainable synthetic fuels when produced from CO2 and green H2. The synthesis pathway presented here overcomes synthetic problems and includes the reaction of dimethoxymethane (OME1) with molecular gaseous formaldehyde in a novel continuous, anhydrous reaction setup. An initially performed wide batch‐catalyst screening highlighted the salts M[NTf2]x with M = Cu+, Co2+ and Mg2+ as especially interesting catalysts (NTf2 = N(SO2CF3)2). Supported ionic liquid phase (SILP)‐catalysts were prepared on this basis and demonstrated the successful synthesis of OMEn in a continuous process. The SILP‐catalysts immobilized in the IL EMIM[BF4] showed a fast and strong deactivation, but those with the IL EMIM[NTf2] showed excellent catalytic performance and stable results in continuous operations exceeding 19 h. The influence of the weight hourly space velocity (WHSV), the reaction temperature as well as the storage conditions of the catalysts (inert vs non‐inert) were investigated. We also demonstrated that the catalysts can be stored in air for 50 days without loss of activity. The SILP‐catalysts were analyzed by NMR and IR spectroscopy. Furthermore, the thermodynamics of the reaction mechanism of some selected catalysts was calculated by DFT theory to this reaction.
