Organization: ASTM International
Publication Date: 29 July 2002
Status: inactive
Page Count: 3
scope:

This method is for determining the packed apparent bulk density of extruded catalysts. The method is applicable to catalysts conforming to the following approximate dimensions: a maximum diameter of 1/8 inch (3.2 mm) and a maximum average length of 3/8 inch (9.5 mm), with a maximum individual length of 5/8 inch (15.9 mm). Apparent bulk density, referred to as ABD, is an empirical value defined as weight per unit volume. The packed ABD of molecular sieves can be determined using UOP Method 563. The packed ABD of extruded catalyst having larger dimensions, such as poly catalyst, can be determined by UOP Method 762.
