摘要：

SO2 inhibits important three-way or stoichiometric catalytic reactions. Of the noble metals studied (Pt, Pd, Rh, Ir), Rh is particularly resistant to SO2 for NO removal while Pt is strongly inhibited by SO2. This is an important reason why Rh is useful for effective NO control. Ir is particularly effective for converting NO under strongly oxidizing conditions in the presence of SO2. NH3 formation is inhibited by SO2 over the metals studied. Similarly under reducing conditions, propylene conversion is inhibited by SO2 over the metals studied. © 1979.
