Standard Test Method for Determining the Activity and Selectivity of Fluid Catalytic Cracking (FCC) Catalysts by Microactivity Test (Withdrawn 2000)
10-03-2000
31-12-2010
1.1 This test method covers determining the activity and selectivity of either equilibrium or laboratory deactivated fluid catalytic cracking (FCC) catalysts. The activity is evaluated on the basis of weight percent conversion of gas oil in a microactivity unit. The selectivities are evaluated on the basis of weight percent yields of specifically defined products resulting from the catalytic cracking of gas oil.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.
1.3 This standard does not purport to address all of the safety problems, 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.
