The document summarizes a trial evaluation of replacing an existing Nektor catalyst with a Nektor 4G catalyst in a fluid catalytic cracking unit (FCCU). Regular catalyst performance measurements and FCC unit simulations show the Nektor 4G catalyst demonstrates improved metals tolerance, lower coke and gas production, and better bottoms cracking and upgrading compared to the Nektor catalyst. Simulation results also indicate the Nektor 4G catalyst can provide improved unit profitability of 1 million euros or more per year for the refinery. In conclusions, both the online catalyst performance data and FCC simulation confirm the benefits of the Nektor 4G catalyst over the previous Nektor catalyst.

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%.
