Methanation reaction temperature

Web28 mei 2024 · CO 2 methanation (known as Sabatier reaction) which would reduce CO 2 emissions and produce natural gas, is considered to be one of the most effective and practical technologies for CO 2 recycling [4,5,6]. As an exothermic reaction, CO 2 methanation is favored at low temperatures. WebSurface blocking by adsorbed species such as surface formate/carbonate or surface carbon species, which are formed during the reaction, contributes little, as concluded from in situ infrared (IR), temperature-programmed oxidation (TPO), and X-ray photoelectron spectroscopy (XPS) data.

WebA High Pressure Cell/Temperature Programmed Desorption catalytic study showed that the reactivity of Ru nanoparticles for the methanation reaction decreases as the experiment was repeated. The cause of the loss in activity was found to be annealing causing surface reconstruction which was verified by TPD spectra (Fig. 1).
