We must also specify if any ZSM-5 additive in present in the catalyst The ZSM-5 per Unit Mass variable acts as another tuning factor to adjust model yields of the unit We may use an average value or set the ZSM-5 content to 0 if the information is not available. Since we will tune the unit to an actual product distribution, it is not essential that this value is exactly the same as the actual unit. 

We will specify the metal content of the equiUbrium catalyst and equilibrium microactivity test (MAT) value. When we use this option. Aspen H YSYS will automatically calculate the makeup of catalyst required to maintain the equibbrium MAT and keep the metal content on the catalyst fixed. The total catalyst inventory refers to the total amount of catalyst available to the FCC unit. We can now specify the operating variables for the FCC unit model.
