strength of a catalyst in a bed. 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.
