ACT 981

Description:Active Grading - Metal (Silica) Trap
Characteristics:NiMo, Al₂O₃
Shape:Trilobe Extrudates

Thanks to its unique properties, silicones are used from Upstream to Downstream. In Upstream their properties make them suitable for use as drilling fluids, flow improvers whereas in refining, silicones are used as antifoaming agents in delayed cokers,
solvent desalphalting units, solvent extraction units but also as additives in lubricants.

The benefits of silicones end at the Hydrotreater battery limit. Silicon is a well known widespread poison for HPC catalysts.
Axens has recently developped a new series of Silicon trap material (ACT 971, ACT 981 and ACT 991). The surface area and the texture of the supports as well as the formulation have been optmized to maximize the silicon removal and retention without compromising the catalyst Hydrotreating activity.

ACT 981 exhibits a very high Silicon and a high HDS and HDN services making it the catalyst of choice for Naphtha applications where catalyst activity (especially HDN) may become the limiting factor.
