CO₂‐neutrale Fischer‐Tropsch‐Kraftstoffe aus dezentralen modularen Anlagen: Status und Perspektiven

Abstract

Angesichts ausbleibender Erfolge bei der Reduktion der CO2‐Emission im Verkehr treten zunehmend auch synthetische Kraftstoffe aus CO2 und erneuerbarer elektrischer Energie in den Fokus. Für diesen sog. Power‐to‐Liquid(PtL)‐Ansatz werden neben konventionellen Technologien für Großanlagen auch intensivierte Technologien für dezentrale Anlagen in Betracht gezogen. Der Beitrag gibt einen Überblick über den Entwicklungsstand und die Perspektiven kompakter Anlagen für dezentrale PtL‐Verfahren auf Basis der Fischer‐Tropsch‐Synthese.

Fischer–Tropsch Synthesis as the Key for Decentralized Sustainable Kerosene Production

“…An extensive simulation model for a PtL process was developed by König et al [13] with Aspen Plus ® providing conclusions regarding the process internal correlations and overall efficiencies. Studies concerning the decentralization of FT-based fuel production were performed by Kirsch et al [14] providing insights on the current state of technology development by the Institute for Micro Process Engineering of Karlsruhe Institute of Technology and the INERATEC GmbH (Karlsruhe, Germany). The work presented here is an extension of a conference paper [15].…”

“…Although still in the development stage and, therefore, not considered in the process outlined in this paper, the integration of hydrocracking in the FT reactor may, in the future, offer a further opportunity to reduce the plant complexity and enhance the process efficiency [14].…”

“…with m mol as the molar mass (g/mol) where-to account for the methane deviation-all r i,n for n > 1 are multiplied with the FT methane reaction rate according (14), and r i,n is substituted for i = paraffin and n = 1 (15):…”

Challenges and Opportunities to Enhance Flexibility in Design and Operation of Chemical Processes

“…Loewert et al 27 investigate microstructured reactor concepts for the decentralized production of Fischer‐Tropsch fuels from renewable hydrogen and CO 2 , which are in addition characterized by good scalability 28. In experimental studies, the authors were able to couple the operation of the reactor with the profile of a photovoltaics plant directly.…”
