Co2 methanation reaction basics
Did you know?
Methanation is the conversion of carbon monoxide and carbon dioxide (COx) to methane (CH4) through hydrogenation. The methanation reactions of COx were first discovered by Sabatier and Senderens in 1902. COx methanation has many practical applications. It is a means of carbon oxide removal from process gases and is also being discussed as an alternative to PROX in fuel processors for mobile fuel … WebOct 19, 2024 · CO 2 methanation is an exothermic reaction using stoichiometric molar ratios of feed gases (H 2 :CO 2 ), producing H 2 O as a byproduct. The overall reaction of CO 2 hydrogenation into CH 4 can be completed either in one step (Sabatier reaction: CO 2 + 4 H 2 ↔ CH 4 + 2 H 2 O) or in two consecutive steps.
