Predicting Catalyst Extrudate Breakage Based on the Modulus of Rupture. [PDF]

open access: yesJ Vis Exp, 2018
The mechanical strength of extruded catalysts and their natural or forced breakage by either collision against a surface or by a compressive load in a fixed bed are important phenomena in catalyst technology. The mechanical strength of the catalyst is measured here by its bending strength or flexural strength.
