Method and apparatus for selective alcohol upgrading

A method for the conversion of CO2 to alcohols or hydrocarbons, comprising:

• reducing CO2 to a first product mixture comprising:
• an alcohol product mixture comprising one or more alcohols;
• and
• a paraffin product mixture comprising one or more paraffins;
• said reducing step comprising contacting a first gas mixture comprising the CO2 and a
• reduction gas with a first catalyst at a reduction temperature and a reduction pressure;
• optionally separating the alcohol product mixture from the paraffin product mixture;
• dehydrating the alcohol product mixture into an olefin product mixture comprising one or more olefins, said dehydrating step comprising contacting the alcohol product mixture with a second catalyst at an ATO temperature and an ATO pressure;
• oligomerizing the olefin product mixture to a higher olefin product mixture comprising unsaturated paraffins and optionally aromatics, said oligomerizing step comprising contacting the olefin product mixture with a third catalyst at an oligomerization temperature and an oligomerization pressure;
• and
• reducing the higher olefin product mixture to a higher hydrocarbon product mixture comprising unsaturated paraffins, said reducing step comprising contacting the higher olefin product mixture with a fifth catalyst at a olefin reduction temperature and an olefin reduction pressure.

A method for the conversion of CO2, comprising:

• contacting a first gas mixture comprising CO2 and a reduction gas with a first catalyst to produce a first product mixture comprising methanol;
• contacting a second feed mixture comprising methanol with a second catalyst at to produce ethylene and a second product mixture comprising C3 and higher paraffins, olefins, and other hydrocarbons;
• optionally, contacting the second product mixture comprising C3 and higher paraffins, olefins, and other hydrocarbons with a third catalyst to produce jet fuel;
• contacting a third feed mixture comprising ethylene and water with a fourth catalyst to produce ethanol.
