Catalyst Best Practices
Abu Dhabi International Downstream, 10-12 May 2015
Agenda
Takreer are about to commission the EPC FEED of their Atmospheric
Residue Desulphurization Unit (ARDS) which will utilize 3000mt of
catalysts in addition to their RFCC unit. There are three main questions
surrounding the catalyst utilized in the ARDS unit as well as the RFCC
unit:
1. What is the best way to handle and manage the vast
amounts of catalysts in these units?
2. How to optimise the use of these catalysts?
3. How to dispose of vast amounts of catalysts in an
environmentally friendly way?
4. What is the best selection method for optimum catalyst
technology?

Catalyst Handling
One issue for Takreer will be to handle and manage a large
amount of FCC catalyst
Local Production
Investing in Infrastructure
 A local production plant in the Middle East enables catalyst reformulation time to
be reduced from approximately 2 months to 1 week.
This will allow Middle East refineries to quickly optimise their FCC operation.

Delivery: safe, fast, dust-free
 Silo facilities allows fresh catalyst to be delivered by silo truck.
 This improves the working environment by eliminating problems of dust
with the use of super sacks.

Hydroprocessing Catalyst Handling
Partner with a catalyst supplier that has
• loading units that are both (a) very large and (b) have a modular
configuration
• local supplying and storage facilities to offer flexibility in loading and
schedule.
Work with an experienced catalyst handling contractor who has
• loaded and unloaded units of this size previously using proven and reliable
methods for dense loading, and
• worked safely in live plant (ie. when the other modules are still in operation).
Partner with a catalyst supplier on a long term basis.

Optimising Catalyst Usage
A key objective for Takreer is to process resid feedstock in the
FCCU while achieving the highest propylene yield, which
requires the use of different catalyst functionalities
Metals Tolerance
Bottoms Upgrading
 Grace has proposed a finely tuned resid FCC catalyst containing high zeolite
stability and metals tolerance to meet Takreer’s resid feedstock requirements.
 Grace Catalysts incorporates state of the art Vanadium trapping functionality

How to optimize hydroprocessing catalyst use?
Partner with an leading catalyst supplier that has strong technical
service to help manage the run and optimize catalyst life.
This is important for modular operation where the catalyst life of
each module is monitored and optimized separately in order to
achieve constant product properties between the RFCC
turnarounds.

Catalyst Selection
To prepare a proper catalyst selection and
minimize risk following procedure is
highly recommended:
 Physical Testing
 To prevent severe issues in the commercial unit from
problematic attrition resistance as well as fluidisation
properties.
 Catalytic benchscale or riser pilot plant testing
 Deactivation in a robust protocol like CPS-3 after
metals impregnation to e-cat metals level.
 Yield prediction based on constant coke yield
results using state of the art FCC model
 Enables comparison at constant feed rate and heat
balance
 Activity retention is considered at constant CAR
 Provides the accuracy required for unit operating and
performance changes
 Model optimisation of the operation
 To select the most economic catalyst technology
