Abstract: A method for a quick testing of transport properties of samples of a zeolite catalyst has been developed. The method is based on the application of gas-phase chromatography, where the tested sample is used as the stationary phase. Cyclopentene, cyclohexane, and 1,3,5-trimethylcyclohexane were used as the testing molecules. A retention indexes for samples comparison were introduced. The method is sensitive even to small changes in the zeolite structures caused by binding agents and/or alkali metals.
