    Methane influence on catalytic hydrogenation of carbon dioxide

  • Popis výsledku v původním jazyce

    Catalytic hydrogenation of carbon dioxide to methane is nowadays becoming an attractive way to utilize surplus electrical energy produced mainly from renewable energy sources. Catalytic methanation is a reaction of hydrogen and carbon dioxide during which they are converted into methane and water. Hydrogen required for the reaction can be produced via water electrolysis from surplus electrical energy. Biogas is mainly made up of methane and carbon dioxide. It makes it an ideal candidate for catalytic methanation as there is no need to separate carbon dioxide, which results in an overall more effective process. The produced methane-rich gas is either known as renewable natural gas (RNG) or sustainable natural gas (SNG). For example, this gas can be used for propulsion of vehicles or can be injected into the gas network and utilized its storage and transport capacity. Four model gases were tested at gauge pressure of 0.55 MPa. The first model gas served to determine activity and selectivity of the used catalyst. This gas consisted of a stoichiometric ratio of hydrogen and carbon dioxide (4:1). The other three gases consisted of biogas in ratios of CH4:CO2 20:80, 40:60 and 60:40 and hydrogen in a stoichiometric ratio to carbon dioxide. From the experimental results it is apparent that maximum methane production was achieved with the use of a model gas with methane to carbon dioxide ratio of 60:40 at 340 degrees C, were the molar fraction of methane in the product gas was 0.98.
