Standard Test Method for Determining Activity of Fluid Catalytic Cracking (FCC) Catalysts in a Fluidized Bed

Abstract

5.1 The fluidized bed test provides data to assess the relative performances of FCC catalysts. Because results are affected by catalyst pretreatment, feedstock characteristics, and operating parameters, this test method is written specifically to address the accuracy and precision when a common catalyst and oil are tested under the same conditions but at different sites, using Kayser Technologies Advanced Catalytic Evaluation (ACE) unit.4,5 Analytical procedures may vary among the sites. However, significant variations are not expected. Note 1: ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. 5.2 The standard reaction temperature for purposes of the accuracy and precision statement is 532 °C [990 °F]. Other reaction temperatures can be used in practice; however, yield data developed at temperatures other than 532 °C [990 °F] will not be the same. Also, test precision may be different at other reaction temperatures.
