To provide an activity evaluation method for metal-carrying catalysts to accurately and rapidly evaluate the activity of metal-carrying catalysts each comprising an active metal carried on a carrier, and in particular, the desulfurization activity of desulfurization catalysts, and further, a screening method for a metal-carrying catalyst using the activity evaluation method.
This activity evaluation method for metal-carrying catalysts is characterized in that: metal-carrying catalysts each comprising an active metal species carried on a carrier are pre-treated so that they come into an acting state; then, xenon is adsorbed onto the carrying catalysts with at least three different adsorption pressures; and the activity of each of the carrying catalysts is evaluated from the value of c in a theoretical expression, the value of c being found by fitting x and y into the theoretical expression: y = a/x + bx + c, where x is xenon adsorption amount and y is a chemical shift of a peak in a
