Abstract
Oxidative dehydrogenation of propane to propene was investigated over Ba-pr omoted Ni0.9MoO4 catalysts (molar ratio of Ba/Mo: 1%, 3%, 6%, 9%, 12%, 15%) . The selectivity for propene increases with the increasing number of basic sites on the catalyst, and molybdenum ions play an important role in propa ne activation. No significant deactivation of the 6% Ba- Ni0.9MoO4 and Ni0. 9MoO4 at 773 K for 80 h and for 40 h, respectively, appeared, indicating th at the 6%Ba-Ni0.9MoO4 has great advantage over the Ni0.9MoO4.
