Through its wide experience and deep know-how, Shell Catalysts & Technologies offers a range of Guard Beds & Adsorbents which can reduce the possibility of unplanned shutdowns and increasing protections for poison sensitive downstream catalyst units.
Shell Catalysts & Technologies has designed an efficient guard bed to protect downstream catalysts from common poisons, specifically sulfur, arsine, and/or mercury. The adsorbents are designed to operate within the reaction system, at standard operating conditions, eliminating the need for the design of a separate poison guard system.
Sulfur guard bed
Shell Catalysts & Technologies offers a variety of sulfur adsorbents designed to trap specific sulfur species. Sorbents include copper products for light sulfur adsorption and nickel adsorbents for more complex sulfur removal. Shell Catalysts & Technologies also offers absorbent and guard bed solutions specifically for upstream customers in areas such as LPG purification.
