Top Bed Grading that protects


CatGuard® – A top bed grading package to protect your main hydrotreating catalyst bed.

Evonik supplies CatGuard metal traps to offer high capacity for trapping metallic and organometallic elements which are severe poisons for the hydroprocessing catalysts. CatGuard grading are installed on the top of main bed catalysts to provide protection against poisoning while controlling hydrogenation of reactive species (olefins, diolefins) and increasing cycle length of the unit. The quantities and types of CatGuard materials required for optimal reactor performance vary based on feed properties and operating parameters.
