1.1. Automatic attrition fluidized bed tester by air jet for various catalysts including FCC designed to determine the comparative characteristics of attrition.
Automated attrition tester for express determination of various catalysts including FCC designed for fluidized bed cracking.
It is used spherical or irregular parts (sizes from 10 to 180 microns), in a time not more than 20 minutes.
Attrition is achieved by tangentially feeding a moist air jet into a cylindrical abrasion chamber 26 mm in diameter and 50 mm in height. The percentage of fines (less than 20 microns) after a 20 minute test is the Air Jet Abrasion Index (AJI).
