4. Conclusion
There are many aspects to consider when choosing the best oxygen-carrying material for a given process. These materials must resist mechanical wear during circulation between reactors, and remain fluidizable (i.e. avoid attrition and particle agglomeration) while retaining their ability to transfer oxygen after multiple redox reactions (notably by avoiding carbon deposition on active sites) to remain effective oxidizers.
It would appear that further studies are required, in particular on the synthesis of supports enabling the oxygen carrier material to acquire greater robustness. Added to this is the need to find a reasonable compromise between the efficiency of the oxygen carrier according to the process envisaged and its cost price, while complying with environmental, health and safety standards. In recent years, particular interest has been shown in accessible,...
