Propene is after ethene the second most important organic chemical. Since it is currently exclusively obtained from fossil resources, a more sustainable route for its synthesis is desirable, notably using renewables such as ethanol as a feedstock [1]. Microporous HZSM-5 are known to convert ethanol to hydrocarbons up to ~C10 [2]. In order to selectively focus on propylene, ZSM-5 based catalysts were prepared, characterized and tested using a high throughput approach. The aim of this work was to analyze the main parameters
influencing the reaction, notably acidity strength, number of acid sites and textural properties. Furthermore, the understanding of the deactivation mechanism involving trapped hydrocarbons was studied. The corresponding properties were determined by in situ FT-IR, UV/Vis spectroscopy, XRD, TEM, TPR-MS and have been correlated to the catalytic performances.
