Towards improved partial oxidation product yield in mixed ionic-electronic membrane reactors using CSTR and CFD modelling

Perspectives on achievements and challenges of oxygen transport dual‐functional membrane reactors

“…84 Similarly, Sommer et al explored CFD and continuously stirred tank reactor (CSTR) models to enhance the yield of partial oxidation products in mixed ionic electronic membrane reactors utilizing an LSCF disk membrane reactor for OCM. 85 Their studies shed light on the selectivity of carbon products for different reactor configurations and compared the results of the CFD model with a less complex two-chamber CSTR model. The modeling tools can be used to identify optimal operating conditions and the results demonstrated the importance of gas phase chemistry and flow configuration.…”

“…Furthermore, the catalytic nature of MIECs should be taken into account to enhance the product yield in future studies. 85 The continuous development of computational simulations and modeling is vital for supporting the rapid progress in experimental-based membrane materials and technology, particularly in simulating the complex behavior of oxygen permeation in dual-functional membrane reactors. 2,82,86 Nevertheless, there remains a gap in understanding both the stability control of chemical reactions and their influence on membrane performance.…”

Roadmap for Sustainable Mixed Ionic‐Electronic Conducting Membranes

“…Other recent works have featured the CFD modeling of LSCF hollow fiber membrane bundles for oxygen permeation (Figure 6a) [95] and LSCF disk membrane reactor for oxidative coupling of methane. [96] The latter study provided insight on the selectivity of carbon products for different reactor configurations (forward or reverse flow) and the results from the CFD model were benchmarked against those obtained using a less complex two-chamber continuously stirred tank reactor (CSTR) model (Figure 6b). Nevertheless, this area remains quite niche due to the pre-requisite of computation expertise required.…”
