(Test Method)Standard Test Method for Testing Fluid Catalytic Cracking (FCC) Catalysts by Microactivity Test
Standard Test Method for Testing Fluid Catalytic Cracking (FCC) Catalysts by Microactivity Test
SIGNIFICANCE AND USE
5.1 The microactivity test provides data to assess the relative performance of FCC catalysts. Because results are affected by catalyst pretreatment, feedstock characteristics, test equipment, and operating parameters, adherence to this test method is a prerequisite for correct interpretation of results. Apparatus, test conditions, and analytical procedures actually used should closely resemble those described in this test method.
5.2 Caution should be used in interpreting results above 80 mass % conversion due to the significance of overcracking.
SCOPE
1.1 This test method covers determining the activity of equilibrium or laboratory-deactivated fluid catalytic cracking (FCC) catalysts, or both. This is evaluated on the basis of mass percent conversion of gas oil feed in a microactivity unit. The selectivity of FCC catalysts can be determined using Test Method D5154.
1.2 The 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.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This 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.
