Patent ID: 8863701

Claim:
A process for on-board carbon dioxide conversion to a hydrocarbon fuel, the process comprising: extracting thermal energy from exhaust gases of a combustion engine, the combustion engine powering propulsion of a vehicle; separating water and carbon dioxide from the exhaust gases; converting the water and the carbon dioxide to hydrocarbon fuel by performing a reaction that is facilitated by a nano catalyst, the reaction being stimulated by the thermal energy extracted from the exhaust gases; and feeding the hydrocarbon fuel into the combustion engine for combustion; where the hydrocarbon fuel comprises ethanol and propyne, and where the reaction is 5CO 2 +5H 2 O→C 2 H 5 OH+H 3 C—C≡CH+7O 2 , where CO 2 is the carbon dioxide, H 2 O is the water, C 2 H 5 OH is the ethanol, H 3 C—C≡CH is the propyne and O 2 is oxygen.
