NOVELTY - Reprocessing of the combustion products such as carbon dioxide (2) and water (3) in renewable synthetic fuel and fuel comprises mixing of hydrogen (6) with carbon dioxide to obtain carbon dioxide-hydrogen mixture (8); preheating the mixture in a high temperature recuperator, and heating the mixture at 800-5000 degrees C; cooling the mixture under the separation of the reaction mixture; heating the carbon monoxide-carbon dioxide-hydrocarbon mixture by Fisher-Tropsch- or methanol- synthesis; converting the obtained mixture into products of hydrocarbon and/or methanol.    USE - The process deals with the reprocessing of the combustion product such as carbon dioxide and water in renewable synthetic fuels and fuels.    ADVANTAGE - The reprocessing of the combustion products takes place completely without consuming high time, energy and chemicals.    DETAILED DESCRIPTION - Reprocessing of the combustion products such as carbon dioxide (2) and water (3) in renewable synthetic fuel and fuel using electrical energy (1), comprises mixing of hydrogen (6) with carbon dioxide in a molar ratio of 1-3.5 to obtain carbon dioxide-hydrogen mixture (8), where the hydrogen is obtained by the electrolysis of water, preferably water vapor; preheating the mixture in a high temperature recuperator, and heating the mixture at 800-5000 degrees C in an electric device or an electrical plasma generator, where a self-forming synthesis raw gas recuperative is used for preheating the mixture; cooling the mixture under the separation of the reaction mixture; heating the carbon monoxide-carbon dioxide-hydrocarbon mixture by Fisher-Tropsch- or methanol- synthesis; converting the obtained mixture into products of hydrocarbon and/or methanol; and optionally condensing the mixture under the separation of water.
