Claim 1:
2. A process for the production of synthetic paraffinic kerosene comprising:
a. using low carbon electricity in an electrolyzer to convert an electrolyzer feedstock comprising water to a first electrolyzer product stream comprising hydrogen and a second electrolyzer product stream comprising oxygen;
b. mixing at least a portion of the first electrolyzer product stream with carbon dioxide to produce an RWGS reactor feed stream;
c. feeding the RWGS reactor feed stream to an RWGS reactor to produce an RWGS product stream comprising hydrogen and carbon monoxide;
d. feeding at least a portion of the RWGS product stream to an LFP reactor to produce an LFP hydrocarbon product stream comprising C5-C24 n-alkanes and alkenes, wherein the C5-C24 n-alkanes and alkenes comprise between 40 volume percent and 99 volume percent of the LFP hydrocarbon product stream;
e. feeding at least a portion of the LFP hydrocarbon product stream to a LFP separation unit, wherein the LFP hydrocarbon product stream is separated into at least three LFP separation products, a light LFP separation product comprising C5-C8 n-alkanes and alkenes, a medium LFP separation product comprising C9-C15 n-alkanes, and a heavy LFP separation product comprising C16-C24 n-alkanes;
f. feeding at least a portion of the medium LFP separation product to a hydroisomerization reactor and mixing it with a hydrogen stream to produce a hydroisomerization product stream, wherein the hydroisomerization reactor comprises a hydroisomerization catalyst;
g. feeding the hydroisomerization product stream to a hydroisomerization separation unit to produce at least two separated hydroisomerization produces, a light hydroisomerization product and a heavy hydroisomerization product, wherein the heavy hydroisomerization product comprises C9-C15 branched chain alkanes having a freeze point ranging from −48° C. to −55° C. thereby producing synthetic paraffinic kerosene.
