【Abstract】 The catalytic activity of several metal salts for low-temperature activation of methane in oleum medium was studied. The results show that KBr, Ag₂SO₄, La₂（SO₄）₃, PbSO₄ and HgSO₄ have good catalytic activity in the oxidation of methane to methyl bisulfate and the activity of HgSO₄ is the highest. KNO₃ has the ability to catalytically convert part of SO₂ to H₂SO₄ and slow down the dilution of H₂SO₄.更多还原
