Abstract

La_0.8Cu_0.2MnO₃ and La_0.8Sr_0.2MnO₃ perovskite catalysts were prepared by the co-precipitation method. The resistance of these catalysts to sulfur poisoning was tested via catalytic combustion of toluene. The results show that the perovskite catalysts were poisoned in the presence of SO₂. In the presence of dodecyl mercaptan (C₁₂H₂₅SH), La_0.8Sr_0.2MnO₃ exhibits better resistance to sulfur poisoning than La_0.8Cu_0.2MnO₃. It was determined that the SO₂ deactivation is due to the formation of CuSO₄ on the catalyst surface.
