Overcoming mass-transfer limitations in the Dual Bed Colloidal Suspension Reactor

Devices for Solar-Driven Water Splitting to Hydrogen Fuel and Their Technical and Economic Assessments

“…However this design requires the addition of a redox mediator and porous bridge for transport which introduces additional losses and limitations through media transport rates. 67 Despite being more complex, the Type 2 design avoids the formation and subsequent compression of a combustible hydrogen-oxygen mixture which is a significant safety concern associated with Type 1 reactors. Mitigating risks arising from this hazard may yet incur additional control and gas processing costs not captured in this analysis.…”

Evaluating particle-suspension reactor designs for Z-scheme solar water splittingviatransport and kinetic modeling

“…Fuller [52] evaluated mass-transfer correlations for gas-induced convective mixing in a dual-bed, particle-suspension reactor and determined the steady-state redox shuttle concentration profiles assuming spatially homogenous reaction rates. However, the effects of optical absorption by the particles and the influence of interfacial electrontransfer kinetics on the species mass transport were absent from that study.…”
