ASTM WK34893

    New Test Method for Measurement of Jet Cup Attrition Index of Fluid Catalytic Cracking Catalyst and Catalyst Additives

    (What is a Work Item?)

    Developed by Subcommittee: D32.02 | Committee D32 | Contact Staff Manager


    1. Scope

    1.1 The jet cup attrition test is applicable to fluid catalytic cracking (FCC) catalysts and catalyst additives. 1.2 Applications for other powdered catalyst have been reported in the literature but are not included as a part of this test method. 1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4 This 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 and health practices and determine the applicability of regulatory limitations prior to use.


    17.1Attrition; Jet Cup; Jet Cup Index; JCI; FCC Catalyst; Fluid Catalytic Cracking Catalyst; Catalyst Additives; Powdered Catalyst


    Attrition testing is used to evaluate FCC catalyst from R&D development through manufacture. In use the catalyst produces fines. Excessive fines production is undesirable. This test is used to predict the fines production of a particular catalyst and to control the manufacturing conditions to an attrition specification. Current ASTM attrition tests require 5 hours per sample. This work item reduces that time to less than 1 hour

    The title and scope are in draft form and are under development within this ASTM Committee.
