Thermally integrated process for the production of liquid fuels with a solid oxide electrolyzer

Resumen de: US2025215331A1

Production of fuels from low carbon electricity and from carbon dioxide by the use of a solid oxide electrolysis cell (SOEC) and Fischer-Tropsch is shown. Fischer-Tropsch is an exothermic reaction that can be used to produce steam. Steam produced from the Liquid Fuel Production (LFP) reactor system, where the Fischer-Tropsch reaction occurs, is used as feed to the SOEC. The higher temperature steam improves the efficiency of the overall electrolysis system. The integration of the LFP steam improves the efficiency of the electrolysis because the heat of vaporization for the liquid water does not have to be supplied by the electrolyzer.

The invention relates to the synthesis of urea from ammonia and carbon dioxide, wherein the hydrogen required for ammonia synthesis is obtained both by steam reforming of feed natural gas (grey hydrogen) and by electrolysis of water using electricity from renewable energy sources (green hydrogen). As the proportion of green hydrogen increases, the amount of carbon dioxide formed in the synthesis gas during steam reforming is no longer sufficient for the synthesis of urea.

GREEN HYDROGEN, SYNTHESIS GAS, AND FLUE GAS WITH A REDUCED NITROGEN CONTENT FOR THE SYNTHESIS OF AMMONIA AND UREA

Resumen de: WO2025125180A1

The invention relates to the synthesis of urea from ammonia and carbon dioxide, wherein the hydrogen required for ammonia synthesis is obtained both by steam reforming of feed natural gas (grey hydrogen) and by electrolysis of water using electricity from renewable energy sources (green hydrogen). As the proportion of green hydrogen increases, the amount of carbon dioxide formed in the synthesis gas during steam reforming is no longer sufficient for the synthesis of urea. Therefore, flue gas, which is formed during the firing of the steam reformer and also contains carbon dioxide, is additionally used. After reducing the nitrogen content, the flue gas is fed into the reforming process. The carbon dioxide from the synthesis gas and the flue gas is combined, separated using conventional carbon dioxide scrubbing, and used for the synthesis of urea.
