Propane Dehydrogenation Catalysis of Titanium Hydrides: Positive Effect of Hydrogen Co-feeding

This study investigated non-oxidative propane dehydrogenation over TiH2. It was found that H2 co-feeding positively affected dehydrogenation, improving the propylene formation rate. In situ spectroscopic characterization of TiH2 in the presence of H2 indicated that partially dehydrogenated titanium hydrides are active for dehydrogenation. This study investigated the non-oxidative propane dehydrogenation over TiH2. It was found that the H2 co-feeding positively affected the dehydrogenation, improving the propylene formation rate. In situ spectroscopic characterization of TiH2 in the absence or presence of H2 indicated that partially-dehydrogenated titanium hydrides (TiHX) are active for the dehydrogenation.
