Reaction Mechanism Development for Methane Steam Reforming on a Ni/Al2O3 Catalyst

In this work, a reliable kinetic reaction mechanism was revised to accurately reproduce the detailed paths of steam reforming methane over Ni/Al2O3 catalyst. A steady-state fixed-bed reactor experiment and 1D catalyst model were utilized for task. The distinctive feature is possibility measure axially resolved temperature profile bed, which makes kinetics inside visible. This allows understanding actual influence on system; while pure gas concentration measurements at catalytic outlet show near-equilibrium conditions, inhere presented shows that it insufficient base development close equilibrium data. new experimental data allow achieving much higher quality in modeling efforts. Additionally, by carefully controlling available active surface via dilution experiment, possible slow down conversion rate, helped during adjustment kinetics. To assess accuracy mechanism, monolith from literature simulated. results fitted able predict outcomes various inlet mass flows, temperatures, steam-to-carbon ratios.
