CO2 reduction by H2 into hydrocarbons (CH2).
CO2 reduction by H2 into hydrocarbons (CH2), simplified. July 10, 2025 CO2 reduction by H2 into hydrocarbon (CH2), symplified. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com Abstract. A chain of those four reactions allows at started USD cost 400 /ton H2 to turn it in 90 OPEX at the end, CO practically free. Heat of exotermic reactions can be converted in electricity and sold, so drastically deminish a cost of H2, CO, and CH2 down to 3.5 cent/liter. (1) CO2 + H2 = CO + H2O. (2) CO + 1.5 H2O = CO2 + 1.5 H2 + O.25 O2 (3) CO2 + 1.5 H2 + O.25 O2 = CO + 1.5 H2O. (4) CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2. Here, CO2 is free being a circular reagent. (5) CO + 2 H2 = CH2 + H2O, or CO2 + 3 H2 = CH2 + 2 H20. Reference. Really. [1] CO2 mass production from the air very cheaply, judbarovski.blogspot.com/2025/01, posted on 12 January, 2025.
