Amidst the ongoing energy revolution, a shift towards sustainable alternatives is imperative to mitigate environmental impacts and ensure global energy security. Hydrogen, a clean-burning fuel, stands out as a future energy vector. Packed bed chemical looping reforming (PB-CLR) is envisaged to be a pioneering technology in the industrialisation of low-carbon hydrogen production. However, industrialisation of PB-CLR for hydrogen production requires a deeper understanding of reactor temperature profiles, namely, evolution of axial and radial temperature profiles within the packed bed. Existing research lacks comprehensive 2-D modelling data and no examples of experimental data for PB-CLR investigating the physical temperature profiles through these cycles. To bridge this gap, development of 2D and CFD models and the design, construction and operation of a lab-scale PB-CLR reactor was commenced. We now seek to compile and present the 2-D temperature profiles for the Oxidation and Reduction stages of the PB-CLR process from all these perspectives. This work seeks to provide an insight into the thermal dynamics occurring during physical operation of the PB-CLR. The lab-scale PB-CLR rig consists of an oxygen carrier bed with height of 70 mm and diameter of 60 mm, utilising ~200 g of Johnson Matthey material. Temperature is recorded via a system of 4 multipoint thermocouples, resulting in 16 readings throughout the bed. An array of operating conditions will be tested, entailing a range of initial bed temperatures from 500-1000 °C and a range of flowrates (0.5-10 NLPM) and compositions of reactant gases, reflecting the relevant stages of the CLR cycle.
