|Significance and Use|
5.1The jet cup attrition test will provide an estimate of the relative attrition resistance of fluid catalytic cracking (FCC) catalyst, catalyst additives, and catalytic materials.
5.2The test is designed to simulate the attrition a catalyst or additive undergoes in a fluid catalytic cracking unit but at an accelerated rate.
5.3The data from this test can be used to rank catalyst according to attrition rate.
5.4The test requires a relatively small sample size of 5 g [0.175 oz] and a relatively short analysis time of 40 min. This test should be useful to quality control facilities that require fast turnaround time and research and development (R&D) facilities that have limited sample material.
1.1The jet cup attrition test is applicable to fluid catalytic cracking (FCC) catalysts, catalyst additives, and catalytic materials.
1.2Applications for other powdered catalysts have been reported in the literature. The round robin test samples included two FCC catalysts and one powdered alumina.
1.3UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
