Patent ID: 7960441

Claim:
Method for reprocessing the combustion products, carbon dioxide and water, to generate renewable synthetic fuels and motor fuels by means of electrical energy, characterized by mixing hydrogen, produced from water, by electrolysis, and carbon dioxide up to a molar ratio of 1 to 3.5 to obtain a carbon dioxide-hydrogen mixture, pre-heating said mixture in a high temperature recuperator to 600 to 800° C. and then heating it to a temperature ranging from above 800 to 5,000° C. in an electrically-heated device or an electrical plasma generator, thereby forming a crude synthesis gas, containing carbon monoxide, hydrogen, reaction water vapour and uncleaved carbon dioxide, utilizing the crude synthesis gas recuperatively in the high temperature recuperator to pre-heat the carbon dioxide-hydrogen mixture, pre-cooling the crude synthesis gas in a second recuperator, then directly cooling the pre-cooled crude synthesis gas, while the reaction water condenses and is separated from the crude synthesis gas and reheating the water depleted crude synthesis gas, containing carbon monoxide, carbon dioxide and hydrogen, in the second recuperator, and feeding the reheated carbon monoxide-carbon dioxide-hydrogen mixture to a Fischer-Tropsch or methanol synthesis and converting it therein to the products, hydrocarbons and/or methanol, which are cooled while the thereby produced water condenses and separates, whereby the products and are condensed if necessary.
