  abstract     = {{Solketal and oxymethylene ether (OME) are two promising blending candidates for regenerative fuels (e-fuels), which could contribute to a holistic solution to the energy crisis. In this study the thermo-oxidative aging of these two e-fuels in their pure form as well as in binary mixtures with different ratios (3:1, 1:1, and 1:3) (vol%) is investigated. Herein, the reaction networks of the thermo-oxidative aging process of both e-fuels and mixtures thereof is elucidated based on intermediates and decomposition products determined via GC-MS. Furthermore, changes of important fuel-specific parameters like kinematic viscosity and density as well as total acid number during aging have been determined. The 3:1 solketal:OME (vol%) mixture exhibits a higher stability to thermo-oxidative aging than the pure fuel components or mixtures with other ratios. The viscosity value of this mixture is within the DIN EN 590 norm after accelerated aging of 72 h (viscosity (72 h) = 4.25 mm(2)/s)) unlike other blends. The maximum value of the total acid number of this aged mixture reaches only similar to 29 % of the maximum value of aged pure OME and has the lowest value of all mixtures. Furthermore, the formation of a precipitate could be successfully suppressed in the 3:1 solketal:OME (vol%) mixture different from other mixtures. With these findings, this study contributes to the design of new sustainable fuels for the transport sector.}},

  abstract     = {{This article contributes to the ongoing dialogue regarding the future application of renewable e‐fuels as part of a holistic solution to the energy crisis. In order to be able to continue using internal combustion engines in a sustainable manner, it must be ensured that these engines are operated exclusively with renewable, CO<jats:sub>2</jats:sub>‐neutral fuels. One way to achieve this is the use of a fluorescence sensor in the vehicle in combination with fuels that are labeled with a fluorescence marker. This study presents an investigation into the use of the benzophenoxazine dye Nile red as a fluorescent marker for distinguishing fossil from renewable fuels. In addition to assessing the stability of the fluorescent marker against thermo‐oxidative aging, the study probes its antioxidative impact on fuel aging, by comparing unlabeled and with Nile red labeled aged fuels. Furthermore, an examination of fuel‐specific parameters underscores the positive effect of Nile red on fuel stability. A comparison with the antioxidant butylated hydroxytoluene confirms the antioxidant effect of Nile red.}},
