Classification: CPC C  B | IPC B  C

Claim 12:
13. A system for producing jet range hydrocarbons comprising:
a triglyceride source comprising at least one C18:1 fatty acid;
a hydrolysis unit coupled to the triglyceride source and a steam source, wherein the hydrolysis unit is configured to hydrolyze at least a portion of the triglyceride source to produce a free fatty acid stream comprising free fatty acids corresponding to triglycerides in the triglyceride source, wherein the free fatty acid stream comprises at least C18:1 fatty acid;
a separation unit coupled to the free fatty acid stream, wherein the separation unit is configured to separate a majority of the C18:1 fatty acid from the free fatty acid stream to produce a C18:1 fatty acid stream;
an olefin cross metathesis reactor coupled to the C18:1 fatty acid stream, wherein the olefin cross metathesis reactor is configured to react the C18:1 fatty acid with ethylene to produce a stream comprising 1-decene and 9-decenoic acid;
a hydrotreating unit coupled to the stream comprising 1-decene and 9-decanoic acid, wherein the hydrotreating unit is configured to hydrotreat at least a portion of the 1-decene and 9-decenoic acid to produce a hydrotreated product stream comprising decane; and
an isomerization unit coupled to the hydrotreated product stream, wherein the isomerization unit is configured to isomerize at least a portion of the decane to produce an isomerized product stream comprising iso-decane.
