Milestones for successful Refinery Catalyst Testing
Successful catalyst testing requires early planning to allow sufficient time to make necessary arrangements and timely obtain test results.
The proposed milestones and indicative timeline are best practices and should serve as a reference relative to the planned catalyst change out. Catalyst lead-time is typically between 6 and 12 months. The selection process, including testing, should start several months before that.
- Define Milestones Plan
- Initiate Vendor Agreements
- Award Testing Contract
- Perform Catalyst Test
- Select The Best Catalyst
Important to consider at this stage:
- Identify and contact independent testing labs
- Define the catalyst suppliers to be contacted
- Overall required time schedule
- Refineries pay the total cost of the test
- Refineries ask the participating catalyst suppliers to share the costs
- The selected catalyst vendor, or “test winner” pays for the test
Lastly, a Request For Proposal (RFP) at Avantium should be placed. These tests require significant planning and it is important that refineries start early to allow for a proper selection of the catalyst options and testing facility to obtain the test results in time for ordering the catalyst(s).
- Evaluate catalyst vendor claims on activity, selectivity, deactivation, start-of-run WABT, aromatics saturation and hydrogen consumption and compare against the incumbent catalyst.
- Opportunity (crude) feed studies – catalyst flexibility.
- Evaluate regenerated catalysts; refiners are the owners of the spent catalysts that can be regenerated and included in comparative testing to increase confidence in the regenerated material.
- Spot sample activity testing after delivery of catalyst by vendor: presulfided catalysts, regen/rejuvenated catalysts.
- Screening of different types of feeds, i.e. impact of feed properties process parameters and catalyst life; Perform new crude oil feasibility and selection for refinery feedstock on sets of catalysts
- Validate/Verify claims for new vendors in the market
- Stability testing / deactivation studies on sets of catalysts.
- Step out technology options (e.g. dewaxing in ULSD).
- Kinetic measurements, feedstock and contaminant effects.
- Obtain relevant data to support refinery revamps and consideration of alternative feeds.
