“…The increasing time of equilibrium states is observed with the increase of the weight ratio of CuO in the oxygen carriers. The equilibrium times performed in the current work have a great relationship with the residence time in the process of chemical-looping combustion, ,, which may shed light on the design and operation of CLC systems. Taking into consideration the low equilibrium time, the residence time for the oxygen carriers with a lower weight fraction of CuO could not have a large value in the process of CLC.…”

“…Parker et al [ 30 ] used the positron emission particle tracking method to find the residence time of a particle in a closed system. Schnellmann et al [ 31 ] use the particle RTD analysis in the chemical looping combustion process in order to determine the number of tanks required to get complete conversion by comparing the particle mean residence time to its time taken for a particle to react completely. Xu and Bhattacharya [ 32 ] determined the residence time required for complete char conversion in an entrained flow reactor (EFR) by feeding the char repeatedly until a complete conversion is achieved.…”

“…The different regimes are governed by the operating conditions, reflected in a specific ( U , G ) range. The RTD in CFB applications has been studied by mostly tracer experiments. ,− Simulations were also repeated by Shi et al The RTD effect on the chemical conversion in a CFB was investigated for the chemical looping combustion process. The cumulative RTD distribution, expressed as F ( t ), determines the average residence time ( t 50 ). The slope of the F ( t ) curves provides important mixing information since a steeper slope corresponds with a more pronounced plug flow.…”
