Abstract

One-dimensional channel molecular sieves were synthesized and tested as hydrocarbon traps using toluene and ethylene as heavy and light HC probe molecules, respectively. Binary TPD traces of these two gases allow a systematic comparison of the adsorption/desorption behavior of molecular sieves. These results show a drastic difference between molecular sieves with 10 oxygen ring apertures (10R) and 12R. Ammonia TPD traces of the series of 12R molecular sieves allow to rationalize the different ethylene/toluene TPD traces.
