Abstract

See full text

Processes are disclosure which comprise alternately contacting an oxygen-carrying catalyst with a reducing substance, or a lower partial pressure of an oxidizing gas, and then with the oxidizing gas or a higher partial pressure of the oxidizing gas, whereby the catalyst is alternately reduced and then regenerated to an oxygenated state. In certain embodiments, the oxygen-carrying catalyst comprises at least one metal oxide-containing material containing a composition having the following formulas: (a) CexByB′zB″Oδ, wherein B=Ba, Sr, Ca, or Zr; B′=Mn, Co, and/or Fe; B″=Cu; 0.011-x-yNixByO2-*, wherein B=Zr, Ba, Ca, La, or K; 0.02
