Standard Test Method for Determining Activity and Selectivity of Fluid Catalytic Cracking (FCC) Catalysts by Microactivity Test

Importancia y uso:

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. Significant variations in apparatus, test conditions and/or analytical procedures may result in activity and selectivity data which do not correlate with data developed by other laboratories on identical catalyst/feedstock samples.

5.2 The standard method reaction temperature is 516 °C [960 °F]. Other reaction temperatures can be used; however, catalyst selectivity data developed at temperatures other than 516 °C [960 °F] may not correlate with selectivity data developed at 516 °C [960 °F]. Also, precision at other reaction temperatures may change compared to data obtained at 516 °C [960 °F].
