1. 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;
passing said reactor effluent stream to a separation unit to recover a dry gas stream, wherein said dry gas stream is taken from a gas concentration unit of said separation unit;
separating the dry gas stream into a CO2 rich stream and a CO2 lean stream, wherein;
producing methanol from said CO2 lean stream or 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.
