In ASTM D7084, "Determination of bulk crush strength of catalysts and catalyst carriers," the crush pressure required to generate 1 wt.% of fines is determined, where 'fines' are defined as particles passing through a mesh size that is half the diameter of the catalyst pellet. Multiple compression loads are used, and the results are interpolated to determine the pressure that yields 1 wt.%.
The usefulness of catalyst pellet crushing strength as a diagnostic test for catalysts is discussed with reference to examples using industrial catalysts. In particular, the applicability of the technique for (i) re‐use of partially used catalyst charges, (ii) comparison of prospective catalysts and (iii) investigation of the effect on catalysts of probable plant failures is described

Techniques to measure the crushing strength of formed catalyst particles is limited to crushing of individual particles, which may not be related to how the catalyst will crush in a reactor or bed. For some catalysts, such as granules, this technique may be the only viable method for obtaining crushing strength. The production of fines in a reactor is not desired because of the potential of

30.03.1999· Statistics and experiments reveal that the mechanical failure of a spherical catalyst under single-particle crushing strength and bulk crushing strength tests are both brittle fracture and the fact that the single particle strength data follow a Weibull distribution. A model is proposed for the packing of spherical particles, which assumes tetrahedral contact and force transmission between the
CRUSH-BK and CRUSH-SP are dynamometers of general use for compression measurements. As far as catalysts are concerned, the ASTM standard methods ASTM D4179 and ASTM D6175 are recommended. ASTM D4179 refers to tableted pellets, which can be measured in either axial or radial way. As the axial crush strength is much higher, it is not representative of the catalyst behavior in
