Abstract
Catalysts comprising: a ground, spent (de)hydrogenation catalyst material present in an amount of 10 to 70% by weight based on the catalyst, the ground, spent catalyst material comprising iron oxide; and a fresh catalyst material present in an amount of 30 to 90% by weight based on the catalyst, the fresh catalyst material comprising iron oxide, wherein at least a portion of the iron oxide in the fresh catalyst material comprises a phase selected from the group consisting of hematite, potassium ferrite, and mixtures thereof are described along with processes for preparing and using the same.
