ASTM D4164-13

Standard Test Method for Mechanically Tapped Packing Density of Formed Catalyst and Catalyst Carriers

SIGNIFICANCE AND USE
5.1 This test method is to be used for measuring the mechanically tapped packing density of formed particles that will not break up during sampling, filling, or tapping of the measuring cylinder under test conditions.
SCOPE
1.1 This test method covers the determination of the mechanically tapped density of formed catalyst and catalyst carriers. For the purpose of this test method, catalyst particles are defined as extrudates, spheres, or formed pellets of 0.8 to 4.8-mm (1/32 to 3/16-in.) nominal 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.

7. Procedure
7.1 Heat an adequate sample(s) at 400 6 15°C for not less than 3 h. Normally, this treatment can take place in air. However,
in the case of materials that might react with air at elevated temperatures (such as prereduced catalysts) the heat treatment should
take place in an inert atmosphere. After heating, cool the test sample(s) in a desiccator or other suitable container to eliminate the
possibility of moisture adsorption prior to testing.
NOTE 1—These conditions may not be appropriate for all materials.
NOTE 2—Since many catalyst formulations are strong adsorbents, the use of No. 4A indicating (cobalt-treated) molecular sieves as a desiccating
medium is suggested. The desiccant should be regenerated at 493 K (220°C) to 533 K (260°C), as required.
7.2 Pour between 240 and 250 mL of the test specimen carefully into the tared graduated cylinder using a funnel. To ensure
proper level, rotate the funnel while pouring the test specimen. Weigh immediately to the nearest 0.1 g.
