Standard Test Method for Determination of Particle Size and Shape Analysis of Catalyst and Catalyst Carriers by Dynamic Imaging Analyzers

Importancia y uso:

5.1 Particle size and shape are important in predicting the performance of catalytic materials. They influence the bulk density of the final product and thereby the effectiveness of catalyst performance in a reactor.

5.2 In addition to the average particle size, a distribution of particle sizes, aspect ratio, and particle convexity can also be determined.

5.3 This practice may also be followed to analyze catalytic materials for quality manufacturing purposes. Test Method D6299 may be utilized to monitor performance of the analyzer in measuring the size and shape of catalytic materials.
