Notable improvements in this catalyst’s efficiency are essential for its continued use. In order to examine the effect of alkaline earth metals on the catalyst performances in the propane dehydrogenation reaction, a series of Cr/η-Al2O3 were synthesized by the impregnation method. The synthesized catalysts were designated as Cr-T/η-Al2O3, where T represents Ca, Mg, Sr, and Ba.

The findings reveal that the Cr-Ba/η-Al2O3 catalyst exhibits better catalytic performance, with significantly higher propane conversion and propylene selectivity (with initial values of 66 % and 86.2 %, respectively) compared to other catalysts. The enhanced performance is attributed to the increased dispersion of Cr species, stabilization of Cr6+ species, and reducing the total amount of acid sites and strong acid sites, which are crucial for maintaining active sites and minimizing coke deposition.
