Abstract: The performance of protonated, Na-form, and Fe-modified ZSM-5 catalysts in dehydrogenative cracking of LPG to light olefins were investigated. The physico-chemical properties of the samples were obtained by XRD, FTIR, and NH3–TPD measurements. Overall, the acidic properties of the samples were suitable for olefin production so that LPG conversions up to 73.79% and product selectivities up to 67.95% were attained over H-ZSM-5 and Na-ZSM-5 catalysts, respectively. The highest olefins yield was 51.28% indicating a 422% improvement to the corresponding yield of thermal reactions alone.
