Abstract

The present invention relates to a system for producing synthetic fuels, in particular jet fuel (kerosene), gasoline and/or diesel, comprising:

a) an apparatus for separately extracting carbon dioxide and water from ambient air,b) a synthesis gas production apparatus for producing a raw synthesis gas comprising carbon monoxide, hydrogen, carbon dioxide and water, the synthesis gas production apparatus having a supply line for carbon dioxide leading from the apparatus for separately extracting carbon dioxide and water from ambient air, a supply line for air and a supply line for water,c) a separating apparatus for separating carbon dioxide and water from the raw synthesis gas produced in the synthesis gas production apparatus,d) a Fischer-Tropsch apparatus for producing hydrocarbons by means of a Fischer-Tropsch process from the synthesis gas from which carbon dioxide and water were separated in the separating apparatus,e) a refining apparatus for refining the hydrocarbons produced in the Fischer-Tropsch apparatus into synthetic fuels,f) a desalination apparatus for desalinating water, the desalination apparatus having a water supply line from the apparatus for separately extracting carbon dioxide and water from ambient air and a water discharge line to the Fischer-Tropsch apparatus, andg) a water purification apparatus, which comprises a water supply line leading from the Fischer-Tropsch apparatus for purifying water produced therein, the system further comprising a pre-reformer for converting hydrocarbons other than methane into methane, carbon oxides, water and hydrogen and i) a water vapor supply line leading from the water purification apparatus to the pre-reformer, ii) a process gas supply line leading from the refining apparatus to the pre-reformer and/or a return gas line leading from the Fischer-Tropsch apparatus to the pre-reformer and iii) a circulation line leading from the pre-reformer to the supply line for water connected to the synthesis gas production apparatus.
