Pulses of hydrogen can be used to monitor the extent of deactivation in a copper-chromium-silver impregnated charcoal. The technique is fairly simple and rapid and it can be performed at room temperature. For the catalyst/adsorbent system under consideration, the hydrogen probes the impregnated charcoal surface and appears to interact with the deactivation (Cr** plus **3) product. A direct, quantitative relationship was established between the reactivity toward hydrogen and the extent of deactivation.
