Study of the interaction of hydrogen with palladium-containing catalysts of methane oxidation

The reaction of palladium-containing catalysts PdCl₂/SiO₂ ratio of the components 0.3:100 (molar)] with H₂ (300°C) after methane oxidation leads to the formation of RH: methane, ethane, propane, n-butane, and isobutane. The sources of RH are PdC_x — products of incomplete oxidation of CH₄ — as well as organic impurities in silica gel. Additions of NaCl (NaCl:SiO₂ = 7:100) triple the yield of RH. Catalysts with additions of H₂SO₄ (H₂SO₄:SiO₂ = 40.100) are not hydrogenated to RH.L. M.
