High-capacity CO/CO2 methanation reactor design strategy based on 1D PFR modelling and experimental investigation J. CO2 Util. (IF 7.7) Pub Date : 2024-01-08 Andreas Krammer, Katrin Salbrechter, Markus Lehner
An in-depth analysis of oil-cooled and naturally ambient air-cooled fixed bed reactors for catalytic methanation of a feedgas containing CO and CO2 has been performed. Combined investigation of modelling and experiments showed, that small tube-to-pellet diameters ratios and optimized reactor cooling are beneficial for high-capacity CO/CO2 methanation. Very good model accuracy was proven with a 1D approach
