AUTOMATIC ATTRITION TESTER BY AIR JET FOR FLUIDIZED BED CRACKING CATALYSTS BY EXPRESS-METHOD

AUTOMATIC ATTRITION TESTER BY AIR JET FOR FLUIDIZED BED CRACKING CATALYSTS BY EXPRESS-METHOD

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).
Operating conditions

  • environmental temperature from +10 to + 35°C;
  • relative humidity not more than 80% at a temperature of 25°C;
  • atmospheric pressure from 84 to 107 kPa (from 630 to 800 mm Hg);
  • power supply – single – phase AC network with voltage of 230-240V and frequency of 50-60 Hz.
  • Analysis time no more than 20 minutes.
  • Suitable for FCC catalysts (with and without steam) and analogs.Automatically maintains with high accuracy the values of the mass flow of air, humidity, has a system for automatic removal of catalyst residues from the walls of the settling chamber before the end of the analysis, which together provides independence from environmental conditions and has the highest repeatability of analysis results no more than 0,1% and the minimum time to reach the operating mode (no more than 10 minutes) in comparison with all currently produced attrition testers.
  • The unit has wheels with foot operated locks and can be easily moved around the room, i.e. moved out when not needed and roll out for analysis.
  • The unit is equipped with the necessary tools and expendable materials for operation for two years, including replaceable filters.
  • The tester if certified as a test facility.
