Plant and process comprising an autothermal reformer for producing synthetic fuels without emitting carbon dioxide

Abstract

A plant for producing synthetic fuels, in particular aviation turbine fuel (kerosene), crude gasoline and / or diesel, comprises: • a) a synthesis gas production device for production of a crude synthesis gas comprising carbon monoxide, hydrogen and carbon dioxide from i) carbon dioxide, ii) water, iii) methane and / or hydrogen and iv) oxygen, wherein the synthesis gas production device comprises at least one autothermal reformer, wherein the at least one autothermal reformer comprises at least one feed conduit i) for carbon dioxide, ii) for water, iii) for methane and / or for hydrogen and iv) for oxygen, and a discharge conduit for crude synthesis gas, • b) a separation device for separation of carbon dioxide from the crude synthesis gas produced in the synthesis gas production device, having a discharge conduit for carbon dioxide and a discharge conduit for synthesis gas, • c) a Fischer-Tropsch device for production of hydrocarbons by a Fischer-Tropsch process from the synthesis gas from which carbon dioxide has been separated in the separation device, • d) a refining device for refining the hydrocarbons produced in the Fischer-Tropsch device to give the synthetic fuels and e1) an electrolysis device for separating water into hydrogen and oxygen and / or e2) a methane-steam reformer which is electrically heated by induction and comprises at least one feed conduit for methane, for water and for hydrogen, and a discharge conduit for crude synthesis gas, and the plant further comprises at least one first pre-reformer which comprises at least one feed conduit for water / steam, for fuel and optionally for methane, and a discharge conduit that leads into the at least one autothermal reformer.
