“…So wurde die C 4 -C 20 -Fraktion der FT-Synthese als Blending-Komponente für konventionelles Kerosin auf bestimmte Eigenschaften wie Bildung von Rußvorläufern untersucht und als vielversprechend eingestuft. 52) Ein mit der FT-Synthese kombiniertes Produkt-Upgrade (hydrierende Spaltung/Isomerisierung) verspricht, den CO-Umsatz sowie die Ausbeute der flüssigen Zielfraktion zu erhöhen. Ein in diesem Sinn seit einigen Jahren anhaltender Trend geht dahin, die Prozesskette kompakter zu machen sowie Prozessschritte zu fusionieren und damit den dezentralen PtX-Gedanken zu unterstützen.…”

Im Jahr 2020 verkündete die Bundesregierung die nationale Wasserstoffstrategie. Aber nicht erst seitdem erfahren die Power-to-X(PtX)-Technologien Aufmerksamkeit. In Deutschland ist der Aspekt "Power" in den letzen Jahren zunehmend regenerativ geworden.Unterschiedliche "X" -neben Wärme insbesondere grüner Wasserstoff -dringen in die industrielle Anwendung vor. Betrachtet man X als chemische Energieträger, so ist das Wörtchen "to" zentral: Um vom regenerativen Strom zu nutzbaren chemischen Michael Klumpp ist Gruppenleiter für "Katalytisch aktive Schichten" am Institut für Mikroverfahrenstechnik, Karlsruher Institut für Technologie (KIT).

“…The liquid phase directly after the phase separation step was selected as a representative for an intermediate from the Fischer-Tropsch process. In Figure 1, the extraction is located between the synthesis step and the product upgrading and refining step [27]. Based on this fuel, the combustion relevant parameters like ignition delay time and laminar flame speed were measured using shock tube experiments and a laminar conical burner experiment [28,29].…”

The Future Fuels project combines research in several institutes of the German Aerospace Center (DLR) on the production and use of synthetic fuels for space, energy, transportation, and aviation. This article gives an overview of the research questions considered and results achieved so far and also provides insight into the multidimensional and interdisciplinary project approach. Various methods and models were used which are embedded in the research context and based on established approaches. The prospects for large-scale fuel production using renewable electricity and solar radiation played a key role in the project. Empirical and model-based investigations of the technological and cost-related aspects were supplemented by modelling of the integration into a future electricity system. The composition, properties, and the related performance and emissions of synthetic fuels play an important role both for potential oxygenated drop-in fuels in road transport and for the design and certification of alternative aviation fuels. In addition, possible green synthetic fuels as an alternative to highly toxic hydrazine were investigated with different tools and experiments using combustion chambers. The results provide new answers to many research questions. The experiences with the interdisciplinary approach of Future Fuels are relevant for the further development of research topics and co-operations in this field.Synthetic fuels based on renewable energies (RE) are widely seen as a key element to achieving climate-neutral transport (e.g., [1,2]). As liquid hydrocarbons have a high energy and power density, they are primarily discussed as fuels for (heavy) road vehicles, ships, and aircraft. Due to their low storage and transport losses, they are also conceivable as a complementary long-term electricity storage option [3]. The challenges of producing and implementing these fuels are manifold. Chemical processes and renewable electrical or thermal energy can be used to produce liquid hydrocarbons from various carbon sources and hydrogen (and sometimes oxygen). Synthetic fuels have several advantages: they can be easily integrated into our existing energy and mobility infrastructures, can be used in all areas of the transport sector, and they can be optimized with regard to their chemical properties. The main disadvantages are the high energy losses and production costs.In this research context, eleven research groups at the German Aerospace Center (DLR) are working together on the Future Fuels project on synthetic fuels. The aim of the interdisciplinary approach is to realize synergies and joint research activities, as well as new research impulses through different perspectives. The scientists and engineers are investigating how synthetic fuels can be produced using solar energy and electrolysis processes (Solar Fuels), and are developing concepts for the re-conversion of these fuels into electricity. They are working on emission-optimized fuels for transport and aviation (Designer Fuels), as well as advanced space ap...

“…Synthetic liquid fuels possess all the positive properties of fossil liquid fuels, such as a high volumetric energy density and easy distribution via existing infrastructures. In addition, they even burn with lower emissions (NOx, Sulphur, soot) [10][11][12].…”

“…Water or steam electrolysis to provide hydrogen in combination with the Reverse Water-Gas-Shift Reaction (RWGS) (Eq. 1) is one option to provide synthesis gas (hereafter referred to as syngas), a mixture of H 2 and CO, as reactant for the FTS [10,11]. The FTS is a heterogeneously catalyzed surface polymerization reaction, which converts syngas into a wide range of hydrocarbons of different chain length.…”
