Catalytic Bed Protectant For Hydrogenation Units

1. Suitable for hydrogenation units with varieties of oils, loaded at the top of catalyst bed, partly or completely replacing ceramic balls and porous filler, to remove and deposite metal ions, especially iron in catalyst voids, avoiding coking and hardening of hydrotreating catalysts, inhibiting rise in bed pressure drop and extending unit cycle length.

Product introduction

Features:

1. Excellent hydrodemetal activity, especially for iron and calcium ions; large pore volume and high dirt capture ability ensure effective removal of mechanical impurities in the feeds; effectively preventing downstream hydrotreating catalysts and extending unit cycle length.

2. High strength, excellent coke resistance.
