Process for increasing liquid fuel yield from carbon oxides

A process for production of a liquid fuel from carbon oxides, comprising:

• contacting a hydrocarbon feed stream with a catalyst in a reactor to produce a reactor effluent stream;
• separating a dry gas stream taken from said reactor effluent stream into a CO2 rich stream and a CO2 lean stream;
• generating a syngas stream comprising one or more of carbon dioxide, hydrogen, carbon monoxide, and water vapor, from said CO2 lean stream;
• producing methanol from said syngas stream and said CO2 rich stream;
• contacting said methanol with an MTO catalyst to produce an olefin stream;
• and
• oligomerizing said olefin stream with an oligomerization catalyst in an oligomerization reactor to produce an oligomerized olefin stream;
• and
• hydrogenating said oligomerized olefin stream to provide a sustainable aviation fuel stream.

A process for production of a liquid fuel from carbon oxides, comprising:

• contacting a renewable feed stream with a catalyst in a reactor to produce a reactor effluent stream;
• separating a dry gas stream and one or more of propylene, butylene, gasoline, heavy oils and marine fuel from said reactor effluent stream;
• separating said dry gas stream into a CO2 rich stream and a CO2 lean stream;
• producing methanol from said CO2 rich stream and CO2 lean stream;
• contacting said methanol with an MTO catalyst to produce an olefin stream;
• oligomerizing said olefin stream with an oligomerization catalyst in an oligomerization reactor to produce an oligomerized olefin stream;
• and
• hydrogenating said oligomerized olefin stream to produce a sustainable aviation fuel stream.
