1. A process for the production of liquid fuels comprising:
a. a first electrolysis feed stream comprising steam is fed to a solid oxide electrolyzer;
b. a second electrolysis feed stream comprising carbon dioxide is fed to a solid oxide electrolyzer,
c. low carbon electricity is used in the solid oxide electrolyzer to produce a first electrolysis product stream comprising a mixture of hydrogen and carbon monoxide and a second electrolysis product stream comprising an oxygen-enriched sweep gas;
d. the first electrolysis product steam is cooled to a temperature of less than 200° C. to produce a cooled syngas stream;
e. the cooled syngas stream is fed to a syngas conditioning block to produce a syngas conditioning product stream comprising hydrogen and carbon monoxide where the molar ratio of hydrogen to carbon monoxide is between 2.0 and 2.2 with a pressure of between 250 psig and 400 psig;
f. the syngas conditioning product stream is fed to a liquid fuel production reactor wherein an exothermic chemical reaction allows the conversion of hydrogen and carbon monoxide to liquid fuel production reactor product comprising a liquid hydrocarbon comprising alkanes with carbon numbers from 5 to 23;
g. wherein the liquid fuel production reactor comprises:
i. a tubular fixed bed catalytic reactor and wherein the tubular fixed bed catalytic reactor allows a Fischer-Tropsch reaction;
ii. a steam boiler surrounds the tubular fixed bed catalytic reactor and the boiler is filled with a mixture of steam and liquid water wherein the boiling of the liquid water allows heat to be removed from the tubular fixed bed catalytic reactor and the boiler produces a medium pressure steam;
h. wherein at least a portion of the medium pressure steam is used as the first electrolysis feed stream.
