摘要: A Frequency Response Method based on the infrared measurement of sample temperature has been developed for adsorption kinetics measurements. It consists in modulating experimental chamber volume at constant frequency. The complex ratio response over pressure is independent time but a function frequency depending all parameters system. This method accurate and allows to measure very fast kinetics. Its major drawback that spurious signal observed high absence adsorption. results obtained with silicalite-propane NaX-carbon dioxide are compared from other techniques (NMR, permeation, etc.).
