Analysis of dry reforming of methane under different fluidization regimes using a multiphase particle-in-cell approach

In the present study, dry reforming of methane (DRM) has been simulated in fluidized-bed reactors using multiphase particle-in-cell model. The model was meticulously built to investigate effect a wide range superficial gas velocities covering particulate, aggregative, and lean-phase flow regimes on bed hydrodynamics, conversion, yields product gases. Constant values for catalyst loading, CH 4 :CO 2 :N ratio (1:1:1.3), properties were maintained all simulations. simulation results obtained are good agreement with experimental data reported literature. show that under different velocities, conversion is relatively indiscernible particulate regime. contrast, inhomogeneous phases, turbulent-fluidized had best reactor performance high CO rates, + H productivity, CO/H molar ratio. This due vigorous turbulent gas–solid contact. Due bypassing backmixing triggered by bubbling, bubbling-fluidized generally worst below fast-fluidized bed. study demonstrates DRM reactions strongly related hydrodynamics. Moreover, it shows significance velocity yield, overall performance.
