Abstract
This paper presents a one-dimensional isothermal model of a hydrogenpermeable circulating fluidized bed membrane reactor (CFBMR) for hydrogen production via steam reforming of methane (SRM). Dynamic simulations were conducted to evaluate hydrogen molar flow rates on the permeation and shell sides at different outlet temperatures. Model validation was performed by comparing the predicted methane conversion with optimized reference data. Additionally, axial profiles of the molar flow rates of CH₄, H₂O, H₂, CO, and CO₂ along the shell side were analyzed at t=14 s. The effects of temperature and reactor zone on hydrogen production were also assessed.
