Title:
担持金属触媒の活性評価方法及びそれを用いた担持金属触媒のスクリーニング方法
Document Type and Number:
Japanese Patent JP4160540
Kind Code:
B2
Abstract:

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 a129Xe NMR spectrum of each of the carrying catalysts with xenon adsorbed thereonto at the different adsorption pressures.
