Carbon fiber that can be renewably or partially renewably produced from CO2 using a combined production method

摘要

The present invention describes carbon fibers produced from CO2 based on different process chains. These are via natural resources such as algal biomass to produce carbon fiber precursors such as PAN from CO2, as well as through Fischer-Tropsch synthesis which is also used to make CO2 carbon fiber precursors. Including purely synthetic routes. In this way, the anthropogenic CO2 is converted into a solid agglomerate state of carbon fiber, which, after being used as a very valuable building material for industry and people for the construction of buildings and vehicles, has a long lifespan. Can be discarded at the end of the cycle. These processes produce by-products such as biodiesel and nutrients that create added value. The resulting material production should be controllable by combining the methods presented in this application. Some of these processes alone have no long-term climate relevance due to high costs, but in the early stages of such development with the aid of a carbon dioxide test certificate or sociopolitical need. They themselves are made from CO2 and have at least the qualities used in the construction business, for example, replacing steel, in that the paradigm of today's material fabrication that is CO2 positive can change in reverse It is possible to quickly show that a carbon fiber building material can be made. If these processes can be linked, which have the disadvantages of large area consumption on the one hand and a longer lack of energy efficiency on the other hand, they can support each other. By combining methods, land use and costs can be adjusted to current regional economic trends based on the future material paradigm of carbon-negative generation of carbon fiber and also in response to current developments in CO2 emission allowance prices . The present invention relates to climate change, which results in the transfer of advanced technology to the currently disadvantaged areas of the world, which drives the economic development of today's disadvantaged areas, and especially creates the urgently needed jobs in these areas. Has the desired effect on policy.
