A bag of catalyst has recently been delivered to ACE Pte. Ltd The Certificate of Analysis of the catalyst provides the particle size distribution by dynamic light distribution, as laid out in Table Fv is the cumulative volume distribution normalized of the particles, and x is the diameter in micrometer.
Part
As the catalyst will be used in fluidized bed reactors, it is necessary to determine its surface volume mean for further calculations.
Using the cumulative volume distribution given, determine the
a the harmonic mean of volume distribution,
b the arithmetic mean of surface distribution, and
c the surface volume mean.
All values should be calculated using appropriate conversions from the cumulative volume distribution values given. An Excel spreadsheet should be used for the calculations.
Hint: Make use of the general equation and table from the textbook, given in the next page.
