Sustainable aviation fuels (SAF) can already be produced today from various biogenic and non-biogenic feedstocks by biochemical or thermochemical processes or a combination of these. In contrast to non-biogenic fuels, biogenically produced fuels and energy carriers are already being produced today in large quantities and used as an energy source. In addition to hydrogenated ester and fatty acid (HEFA)-based SAF, these include biogas and bioethanol, which are used today in particular in heat generation, electricity generation or road transport. In addition, there are other biogenically produced intermediates, such as 2,3-butanediol, which can be used to produce an SAF.
Against this background, a comparison of different SAF production routes based on the current industrially available products biogas and bioethanol, as well as a possible production of 2,3-butanediol to SAF with technical key figures will be evaluated against each other. The goal is to focus on processes with a maximization of the carbon yield without considering CO2 reduction with hydrogen and thus a combined biological and non-biological process. Thus, the installation of large amounts of renewable power generation is not required explicitly for SAF production and a potentially faster availability of larger SAF quantities could be achieved. To achieve this goal, the first processes are designed on the basis of a detailed literature research and evaluated with regard to their carbon efficiency. In the process route based on biogas as feedstock, carbon activation must first be achieved by reformation. The resulting synthesis gas can be further processed via the methanol or the Fischer-Tropsch pathway. Since the methanol intermediate is already available on an industrial scale - albeit from fossil sources - the methanol process route is considered, since this results in an independence of the various process steps. The alcohol-to-jet process designs and concepts are then analyzed for the ethanol and for the intermediate product methanol process route.
