Abstract
This research describes the synthesis of iron-doped zeolitic catalysts for the transformation of propane to propylene. The goal of this research is to develop a dehydrogenation catalyst to convert shale-gas derived cheap propane feedstock to economically valuable propylene, while at the same time making this catalyst sustainable and non-toxic to the environment. Fedoped zeolitic frameworks have shown promising activity in percentage of conversion and in selectivity. In our study we analyzed zeolites ZSM-5 and AIP0-5. These were chosen because they have differences in pore structure , channel sizes, and connectivity between channels. Most importantly the differences in the chemistry as ZSM-5 is pure silica (Si - 0 - Si) framework and AIP0-5 is Al-0-P network. These differences allow propane dehydrogenation to be done to their Fe-Doped doped frameworks while being able to understand selectivity based on the different structures of the pores and channels. In this presentation, we will present preliminary data on the successful synthesis of these materials by hydrothermal route and characterization by powder X-ray diffraction, IR- and Mossbauer spectroscopy.
