Parametric study of hydrogen production via sorption enhanced steam methane reforming in a circulating fluidized bed riser

Modelling of Sorption-Enhanced Steam Reforming (Se-Sr) Process in Fluidised Bed Reactors for Low-Carbon Hydrogen Production: A Review

“…This is different from the multi-fluid/three-fluid model where conservation equations are solved for all the phases involved in the processone gaseous phase and two solid phases (catalyst and sorbent). However, in most cases, the sorbent and catalysts are assumed to have the same properties and constant size [110][111][112][113][114][115][116][117]. CFD simulation of SE-SR in fluidised bed reactors have been carried out based on different levels of model complexities; usually based on phase description and spatial dimensions (1D, 2D and 3D) of the computational domain.…”

“…Similarly, Phuakpunk et al presented a simple 2D two-fluid model to simulate SE-SR of methane [111] and ethanol [120] in the riser of a CFB reactor. As with some other works, model validation was comparable for hydrogen output but showed great deviation for CO 2 concentrationabout 40 %.…”
