Standard Guide for Determination of Individual Particle Strength of Low Surface Area Catalysts and Catalyst Carriers by Drop Test onto a Steel Plate

Importancia y uso:

5.1 This guide is intended to provide information concerning the ability of formed catalysts or catalyst carriers to resist particle size reduction during use. It can be used by itself or in conjunction with other methods to assess catalytic material integrity, such as Test Methods D4058 and D7084.

5.2 There are no known restrictions on sample geometry, as spheres, pellets, and hollow cylinders are suitable for testing.

5.3 This guide, as written, is suitable for use for catalytic materials from about ¹/₈ in. to about ³/₄ in. It can also be used for larger parts, but this requires using a larger diameter pipe.

5.4 This guide is suitable for specification acceptance, manufacturing control, and research and development processes.
