Measurement of heterogeneously catalyzed gas reactions by DSC

  • G. Hakvoort
Organic Chemistry

Abstract

Gas reactions, catalyzed by solid catalysts, can be measured by DSC. In the experimental set-up an open sample pan with catalyst (powder or pellet) is placed on the sample side of the DSC sensor. The reactive gas mixture flows through the cell and reacts on the catalyst surface. The heat effect, caused by this reaction, results into a DSC signal.

The calibration procedure is described for quantitative evaluation of the DSC measurements. For illustration four different reaction systems are discussed.
