| Catalyst | Type/Applications | Description |
| SENTRY™ OptiTrap Series - Medallion, MacroRing, Ring, Filterlobe | Pressure Drop Control/Filtration - Hydrotreating applications | SENTRY* OptiTrap deep bed filter systems employ inert and catalytically active shaped, high
void aluminas to maximize the fouling tolerance of a hydroprocessing unit reactor. |
| SENTRY™ InterLayer | Pressure Drop Control/Filtration - Hydrotreating applications | SENTRY* InterLayer catalysts are durable trilobe nickel molybdenum (NiMo) and cobalt molybdenum (CoMo) promoted catalysts designed for size grading between small diameter catalysts and larger reactor support media. |
| SentrySupport[Active] | Active Support - Hydrotreating applications | SentrySupport[Active] is a durable, spherical nickel molybdenum promoted active support designed to provide the foundation for hydroprocessing reactor catalyst loads. |
| SentrySupport[Inert] | Inert Support - Hydrotreating applications | Durable, spherical inert ceramic support designed to provide the foundation
and support for hydroprocessing reactor catalyst loads. This product is designed to withstand the most severe environments. |
| SENTRY™ MaxTrap[As] | NiMo - Hydrotreating applications- Arsenic trap | A trilobe nickle molybdenum promoted catalyst on a high surface area alumina extrudate specially formulated to trap Arsenic (As) present in a wide range of petroleum feedstocks. Protects high activity catalysts for significantly longer periods from arsenic poisoning. Demonstrates exceptional stability in this severe environment.
