OSC Measurements at Low Frequency

Oxygen Storage Capacity may be determined under dynamic conditions according to the method introduced by Yao and Yu Yao [1] and further adapted by Duprez [2]. 

Two different measurements of the oxygen storage capacity may be distinguished  

OSC and OSCC measurements can be carried out in a pulse chromatographic system which was described earlier [2]. The experimental setup is schematized below on Fig. 7.1. 

Oxygen Storage Capacities may be measured in many different ways depending on the operating conditions but also on the nature of the reducer and the oxidant. Four different combinations are reviewed hereafter. 

The most common oxidant/reducer system is probably the one where CO is used as the reducer and O2 as the oxidant.
