Activation by O₂ of Ag_xPd_1-x Alloy Catalysts for Ethylene Hydrogenation.

ABSTRACT: A composition spread alloy film (CSAF) spanning all of Ag_xPd_1-x composition space, x_Pd = 0 → 1, was used to study catalytic ethylene hydrogenation with and without the presence of O₂ in the feed gas. High-throughput measurements of the ethylene hydrogenation activity of Ag_xPd_1-x alloys were performed at 100 Pd compositions spanning x_Pd = 0 → 1. The extent of ethylene hydrogenation was measured versus x_Pd at reaction temperatures spanning T = 300 → 405 K and inlet hydrogen partial pressures spanning P_H2ⁱⁿ = 70 → 690 Torr. The inlet ethylene partial pressure was constant at P_C2H4ⁱⁿ = 25 Torr,
