Catalyst Grading & Poison Control
Catalyst contamination is a costly yet increasingly common issue that plagues hydroprocessing units. Because many contaminants can cause severe catalyst poisoning, they can negatively impact ROI. Shell Catalysts & Technologies offers a portfolio of protective solutions to reduce the effects of these contaminants.
Protective Solutions for Catalyst Grading
Opportunity feed sources have extended the range of poisons that hydroprocessing unit operators must face. Shell Catalysts & Technologies has committed unique R&D resources to solve the contaminant problems refineries face every day in order to protect catalyst investment and, ultimately, refineries鈥 bottom lines.
Shell Catalysts & Technologies offers SENTRY鈩 Guard Catalysts and Support 鈥 an entire portfolio of solutions that prevent, diagnose, and resolve contaminant issues commonly seen among hydroprocessing units. By implementing SENTRY鈩 technology, unit operators can thwart contamination effects on catalysts and therefore process higher quality feeds.
Prevention
SENTRY鈩 Guard Catalysts and Support products are dedicated to protecting hydroprocessing operations from potentially harmful feedstock contaminants. These products use Shell Catalysts & Technologies filtering infrastructure to prevent contaminants from poisoning catalysts and sabotaging catalyst ROI.
- SENTRY鈩 OptiTrap Series - Medallion, MacroRing , Ring, Filterlobe
- Deep bed filter systems that use inert and catalytically active shaped, high-void aluminas to maximise fouling tolerance
- SENTRY鈩 InterLayer
- Durable NiMo- and CoMo-promoted catalysts designed for sise grading between small diameter catalysts and larger reactor support media
- SentrySupport[Active]
- Spherical NiMo-promoted active support designed to provide the foundation for hydroprocessing reactor catalyst loads
- SentrySupport[Inert]
- Inert ceramic support designed to withstand the most severe hydrotreating environments
Resolution
Some hydroprocessing units currently have systems in place that allow for contaminants to poison catalysts. These SENTRY鈩 Guard Catalysts and Support products maximise trapping technology to eliminate entrainment of unwanted elements in feedstocks, improving the quality of the feeds.
