摘要
The performance of protonated, Na-form, and Fe-modified ZSM-5 catalysts in dehydrogenative cracicing 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.
