Temperature-programmed Reduction, Oxidation and Sulfidation

Temperature-programmed reaction methods form a class of techniques in which a chemical reaction is monitored while the temperature increases linearly in time. Several forms are in use temperature-programmed reduction, oxidation and sulfidation. 

The instrumentation for temperature-programmed investigations is relatively simple. The reactor, charged with catalyst, is controlled by a processor, which heats the reactor at a linear rate of typically 0.1 to 20 °C min . A thermal conductivity detector or, preferably, a mass spectrometer measures the composition of the outlet gas.
