USE OF REDOX MASS HAVING A SPINEL TYPE STRUCTURE FOR A LOOPING REDOX PROCESS

摘要

The invention relates to the use of a novel type of active mass in looping redox processes. Said mass contains a spinel of formula Cu_1−xFe_1+xAlO₄ with 0≦x≦0.1. The active mass according to the invention has a high oxygen transfer capacity and improved oxidation and reduction rates.
