CO₂ methanation (e-fuels / power-to-gas)
The Sabatier reaction (CO₂ + 4H₂ ⇌ CH₄ + 2H₂O) converts captured CO₂ and green H₂ into synthetic natural gas at a 97% single-pass-equivalent conversion (real plants stage several adiabatic beds with intercooling to reach this; lumped into one reactor here), then a cooler and knockout drum condense the reaction water from the SNG — the e-fuels loop that closes the loop on captured carbon instead of just storing it.

Bio-ethanol is catalytically dehydrated to ethylene, oligomerized toward a decene-range olefin, then hydrogenated to n-decane — a real synthetic paraffin in the SAF/jet-range carbon-number band.

View & opene-Fuels (Power-to-Liquids): rWGS + Fischer-Tropsch
The Power-to-Liquids / e-SAF pathway: captured CO₂ and green hydrogen are converted to synthetic hydrocarbons. A reverse water-gas-shift reactor turns CO₂ + H₂ into CO + H₂O (solved to real chemical equilibrium), the water is knocked out, and the syngas feeds a Fischer-Tropsch reactor that builds a whole hydrocarbon slate via the Anderson-Schulz-Flory chain-growth law. The single knob that sets the product spectrum is the chain-growth probability alpha (here 0.90): a high alpha shifts the slate toward diesel/wax, a low alpha toward LPG/naphtha — the reactor distributes the reacted carbon across n-paraffins C₁..C₈ (the tail lumped as C₈ wax) with exact C/H/O atom balances, so it conserves atoms wherever the distribution is cut.
