文摘

Active component modification of Ag/Al2O3 significantly improves activity. Second metal addition increases the partial oxidation of HC at low temperature. Interaction of second metal and Ag leads to the formation of more Agnδ+ clusters. Support modification of Ag/Al2O3 improves its surface properties and SO2 tolerance. The mechanism of modification of Ag/Al2O3 catalyst is discussed.
