Deep Oxidation of Methane on Palladic Catalysts on Suppliers ZrO2, CeO2, ZrO2-CeO2, CeO2-CuO on Stainless Steel Prepared with the Method of Plasma Drawing

The influence of the nature and the maintenance of the secondary supplier, the contents and the nature of the predecessor of palladium on catalytic activity of Pd/MeOx/Ni-Al/HC catalysts in the reaction of deep oxidation of methane is considered in the work. The secondary supplier was put with the method of a plasma dusting. It is defined that the best predecessor of palladium is [Pd(NH3)4](NO3)2. The minimum concentration of palladium necessary for achievement of full oxidation of methane on the best samples is 0.25%. It is shown that with the increase in the maintenance of ZrO2 the activity grows in catalysts. All catalysts are characterized by the XRF method. The most active sample of Pd/CeO2-ZrO2/Ni-Al/HC is additionally investigated by the method of the scanning electronic microscopy.
