| Summary: | The effect of cobalt addition on the activity of nanocrystalline iron catalysts in the cracking of methane reaction is studied. The composition and properties of the catalyst were determined by inductively coupled plasma optical emission spectrometry, X-ray diffraction and temperature-programmed reduction methods. The activity of the catalyst in the reaction was defined by measuring the concentration of hydrogen, which was determined by gas chromatography. After cracking of methane reaction, the sample coated with a carbon deposit was examined with scanning electron microscope with energy-dispersive spectrometer. The reaction yield in the direction of hydrogen acquisition for the catalyst with cobalt was above 80%, and after the regeneration process, the catalyst was still active at a very high level. The reaction path for the catalyst without the cobalt addition was performed in two steps, and the catalyst after the reaction was non-regenerative. |
