Reactions number choice in numerical simulation of the isobutane dehydrogenation process in a fluidized bed

The dehydrogenation of isobutane in a laboratory-scale fluidized bed reactor is investigated through numerical modeling and computational simulation. The analysis evaluates the impact of secondary reaction pathways on process simulation outcomes, with particular attention to reactor performance metrics. Simulation results demonstrate minimal influence of side reactions on target product yield in laboratory-scale configurations with constrained particle bed heights. However, turbulent fluidized bed regimes operating at elevated velocities exhibit potentially significant deviations, necessitating further investigation of reaction kinetics and hydrodynamics under such conditions. These findings highlight scale-dependent variations in reaction network dominance, suggesting distinct optimization requirements for different fluidization regimes in isobutane dehydrogenation processes. The computational approach provides a framework for evaluating reactor performance across operational scales.
