GRACE Catalyst Trial Evaluation
Agenda
Based on :
• Regular Ecat ACE data analysis
• Raw unit data comparison
• FCCU Performance normalized with FCC-SIM

3. 3
Catalyst Evaluation – Catalyst Evaluation Conditions
Change from Nektor to Nektor 4G
After reaching at least 60% of catalyst change over
catalyst evaluation was conducted

4. 4
Catalyst Evaluation – ACE measurement

5. 5
Catalyst Evaluation - Regular Ecat ACE Data
Nektor 4G demonstrates lower H2, CF,GF and delta coke inferring
improved metals tolerance.

6. 6
Catalyst Evaluation - Regular Ecat ACE Data
Loer CF and GF and hydrogen; Lower coke yieldNektor 4G demonstrates similar selectivities regarding LPG and LCO while
slightly better gasoline selectivity. Bottoms cracking at constant coke is better.

7. 7
Catalyst Evaluation - FCC SIM Simulation
The FCC modelling is based on test-run dated processed by FCC-
SIM.
This analysis is valid if good test-runs are available:
• Feed and product Mass Balance is within ± 2.0 wt%
• Hydrogen balance = +/-4 wt%
• Hydrogen in coke: between 6 and 8%.

Catalyst Evaluation – Feed Quality & Unit Operating Parameters
 Comparison of both catalyst with the same operating
conditions:
 Case 1: Nektor prediction with reference case operating
conditions and Nektor calibration factors
 Predicted: Nektor 4G prediction with reference case
operating conditions and Nektor 4G calibration factors

Conclusions
Regular ecat ACE results shows favorable results for Nektor 4G
compared to Nektor.
FCC SIM evaluation confirms the ACE study (improved unit
conversion and bottoms upgrading)
FCC-SIM allows the refiner to calculate the value generated by
Nektor 4G over Nektor.
