Abstract

The dehydrogenation of propane was studied over chromium-modified MFI-type zeolite catalysts. Three different chromium-modified ZSM-5 zeolites were synthesized following typical hydrothermal synthesis and impregnation procedures and were finally treated hydrothermally at relatively severe steaming conditions. The prepared catalyst samples were characterized by XRD, SEM-EDS, N₂ adsorption/desorption, Ammonia-TPD and ²⁷Al MAS NMR. The catalytic results showed that when chromium species are randomly dispersed within the zeolitic particles act synergistically with the remaining acidic framework Al inducing improved dehydrogenation activity and propylene selectivity.
