N2 - The present work aims at studying low-temperature steam reforming (LTSR) of model mixtures of flare gases containing C2H6-C4H10 in methane excess over a highly dispersed Rh-based catalyst. 1 wt% Rh/Ce0.75Zr0.25O2 catalyst was prepared by sorption-hydrolytic deposition. Catalytic properties were studied in the LTSR of model fuel gas mixtures at 200–350 °C. The catalysts provided complete conversion of C2+-hydrocarbons into CH4, CO2 and H2 at 320–350 °C. The conversion of propane and heavier alkanes over Rh at low temperature (200–300 °C) allows obtaining high ethane concentrations in the products, which is not observed in the case of nickel catalysts. The influence of hydrogenolysis reaction to ethane formation is discussed. Ethane has a higher calorific value than methane and can compensate the negative effect of the product gas dilution by carbon dioxide and hydrogen that are formed in the reaction. This can be useful for adjusting the fuel properties (calorific value, Wobbe index, methane number) of the resulting gas mixtures.
