Abstract
A CO2 conversion method includes: generating CO and H2O by a RWGS reaction from CO2 and H2; generating C2H4 and H2 by CO electrolysis from the CO and H2O; and using the H2 generated by the CO electrolysis as the H2 of the RWGS reaction.
Claims3
A CO2 conversion method comprising:
- generating CO and H2O by a RWGS reaction from CO2 and H2;
- generating C2H4 and H2 by CO electrolysis from the CO and H2O,
- wherein CO consumption/H2 generation is in a ratio of 1 mol/1 mol;
- and
- using the H2 generated by the CO electrolysis as the H2 of the RWGS reaction, wherein a C2H4 current efficiency in the CO electrolysis is 66.6% or less.
