Expert Solutions for Customized Performance – Precision Tuned Stacked Catalyst Systems

  • Catalyst technology has developed by leaps and bounds in the last two decades. This has been driven by many factors; the switch to ULSD, increases in required performance and increasing demand for distillate yield.
  • Catalyst technology companies have been introducing a new line of catalysts every 4 – 5 years to improve HDS, HDN and hydrogenation activity. Use of these products alone provides solid performance, but a key feature of these products is their synergistic behavior when expertly applied in a stacked system.
  • This presentation will share case studies where this approach has provided value to refiners all over the world.
