Webfor the CO and H2 formation at temperature as high as 900K. It was suggested that reverse water gas shift reaction was involved in the reaction pathway over Pt. Pd catalyst showed lower activity for CO and H2 formation. On the other hand, only CO2 and H2O were produced by the complete oxidation of CH4 over Fe and Co catalysts. WebMay 20, 2024 · Catalytic partial oxidation (CPO) of logistic fuels is a promising technology for the small-scale and on-board production of syngas (H2 and CO). Rh coated monoliths can be used as catalysts that, due to Rh high activity, allow the use of reduced reactor volumes (with contact time in the order of milliseconds) and the achievement of high …
