The selective conversion of ethane into ethylene is currently being studied because of the economic impact of using natural gas and LPG`s raw materials to produce chemicals and polymers. The available technology for the production of ethylene is the steam cracking of ethane, although it is a highly energy-intensive process. Several approaches to this problem have been considered, although oxidative dehydrogenation (ODH) remains prominent. The principal reason for this lies in the fact that dehydrogenation in the presence of oxygen is thermodynamically favored and coking side reactions are minimized. The present note reports preliminary results in the performance for the ODH reaction of ethane of a new family of vanadium-loaded {alpha}-Ti phosphate catalyst. Moreover, although these catalysts show modest activity with negligible production of CO{sub 2}, a second objective was to report data on the genesis of surface sites during on-stream operation.
