Abstract

The work focuses on mimicking the loading of the catalyst pellets into a reactor in a realistic manner and proposing a simple method to predict catalyst bed density using Blender 3D Software, a free and open-source 3D creation suite. The catalyst freely falling into a container was animated. The void fraction of loose and close-packing catalyst bed was compared. The effects of different catalyst shapes (sphere and cylinder) and sizes (2–5 mm) on the catalyst bed density in different reactor sizes (18-50 mm) were investigated. It could well predict the values with the error ranging from 0.36 to 6.59%. The obtained information from Blender was employed in a computational fluid dynamics (CFD) model for simulating hydrogen production in a glycerol steam reformer packed with Co-Ni/Al2O3 catalyst.
