Patent number: 11898275Abstract: The invention describes carbon fibers which are produced on the basis of different process chains from CO2. These include routes through natural resources such as algal biomass to produce carbon fiber precursors such as PAN from CO2, as well as the purely synthetic route via the Fischer-Tropsch synthesis, which is also used to make CO2 carbon fiber precursors. In this way, CO2 from anthropogenic origin is to be converted into a solid aggregate state of carbon fiber, which can be disposed of at the end of its life cycle, after being used as highly valuable building material for industry and man, for the construction of buildings and vehicles. These processes produce by-products such as biodiesel and nutrients that generate added value. The production volumes of the resulting substances should be controllable by combining the methods presented here.Type: GrantFiled: September 28, 2021Date of Patent: February 13, 2024Inventors: Kolja Kuse, Uwe Arnold, Thomas Brück
