Standard Test Method for Mechanically Tapped Packing Density of Fine Catalyst Particles and Catalyst Carrier Particles
|Publication Date:||1 October 2003|
significance And Use:
This test method is for measuring the mechanically tapped packing density of powders that are smaller than 0.8 mm in diameter, such as Fluidized Catalytic Cracking Catalysts (FCC).
1.1 This test method covers the determination of the mechanically tapped packing density of fine catalyst and catalyst carrier particles smaller than 0.8 mm in diameter.
1.2 This standard does not purport to address all of the safety concerns, if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
