NOVELTY - A system comprises a carbon dioxide reduction reactor including a catalyst (c1), for converting a gas mixture (g1) comprising carbon dioxide and a reduction gas into a product mixture (p1) comprising an alcohol product mixture comprising one or more alcohols and optionally a paraffin product mixture comprising one or more paraffins, an alcohol-to-olefin (ATO) reactor including a catalyst (c2), for dehydrating the alcohol product mixture to obtain an olefin product mixture comprising one or more olefins, an oligomerization reactor including a catalyst (c3), for oligomerizing the olefin product mixture to obtain a higher olefin product mixture comprising unsaturated paraffins and optionally aromatics, and an olefin reduction reactor including a catalyst (c5), for reducing the higher olefin product mixture to a higher hydrocarbon product mixture comprising unsaturated paraffins. USE - System is used for converting carbon dioxide into alcohols e.g. ethanol or hydrocarbons e.g. jet fuel (all claimed). ADVANTAGE - The system enables economical conversion of carbon dioxide into alcohols or hydrocarbons with lower carbon dioxide equivalent emissions than the fossil fuel-derived counter-portion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for conversion of carbon dioxide into alcohols or hydrocarbons, which involves reducing carbon dioxide to mixture (p1) comprising alcohol product mixture comprising one or more alcohols and a paraffin product mixture comprising one or more paraffins, by contacting mixture (g1) comprising the carbon dioxide and reduction gas with catalyst (c1) 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 olefin product mixture comprising one or more olefins, dehydrating by contacting the alcohol product mixture with catalyst (c2) 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, oligomerizing by contacting the olefin product mixture with catalyst (c3) at an oligomerization temperature and an oligomerization pressure, and reducing the higher olefin product mixture to higher hydrocarbon product mixture comprising unsaturated paraffins, reducing by contacting the higher olefin product mixture with catalyst (c5) at a olefin reduction temperature and an olefin reduction pressure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic process diagram of the system for coproduction of jet fuel and ethanol.
