Simulation of Sorption-Enhanced Steam Methane Reforming over Ni-Based Catalyst in a Pressurized Dual Fluidized Bed Reactor

Steam methane reforming is a major method of hydrogen production. However, this usually suffers from low energy efficiency and high carbon-emission intensity. To solve issue, novel steam-methane-reforming process over Ni-based catalyst in pressurized dual fluidized bed reactor proposed work. A three-dimensional computational fluid dynamics (CFD) model for the complex physicochemical was built to study characteristics. The first validated against reported data terms hydrodynamics reaction kinetics. Next, performance methane-steam-reforming predicted. It found that methane-conversion ratio close 100%. mole fraction H2 dry-yield syngas reached 98.8%, cold gas 98.5%, carbon-capture rate 96.4%. believed can be used with carbon
