AUTOMATIC ATTRITION TESTER BY AIR JET FOR FCC CATALYSTS FOR FLUIDIZED BED CRACKING BY ASTM D5757-11

NEW GENERATION EQUIPMENT

AUTOMATIC ATTRITION TESTER BY AIR JET FOR FCC CATALYSTS FOR FLUIDIZED BED CRACKING BY ASTM D5757-11

Automatic attrition fluidized bed tester by air jet for various catalysts including FCC designed to determine the comparative characteristics of attrition of FCC by friction of an air jet according to ASTM D5757-11.

It is used for testing with particles of spherical of irregular shape (size from 10 to 180 microns).

Abrasion is achieved by fluidizing the sample with moist air jets. The percentage of fines (less than 20 microns) after the 5 hour test is the Air Jet Abrasion Index (AJI).

  • Strictly complies with the new ASTM method
  • Suitable for FCC catalysts (with and without steam) and analogs.
  • Automatically maintains with high accuracy the values of mass air flow, humidity, has a system for automatic removal of catalyst residues from the walls of the settling chamber before the end of the analysis and a minimum spread of sapphire nozzle diameters that meet the requirements of ASTM 57-57-11, which together provides independence from conditions environment and has the highest repeatability of the analysis results of 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 abrasion 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 is certified as a test facility.
