GSorb-800(arsenic/phosphine removal)

Arsine is one of the most poisons to downstream catalyst in hydrocarbon processing. It can poisons the downstream precious metal catalyst in polypropylene plants if it is present in ppb level in feed stream. Furthermore natural gas frequently contains arsine and other arsenic compounds that some of the type are not effectively removed with a traditional adsorbent. GAHARCERAM provide series 800 adsorbents to meet the update requirements. The choice of suitable adsorbent  as arsine removal depends on the feed stream characteristics, type of impurity to be removed, and the process conditions such as the pressure, temperature, etc


Activated alumina (AA) is the most commonly used adsorbent for the removal of arsenic from aqueous solutions. However, conventional porous solids including AA have ill-defined pore structures and, typically, low adsorption capacities and actually in a kinetically slow manner. An ideal adsorbent should have uniformly accessible pores, and interlinked pore system, a high surface area, and physical and/or chemical stability. To meet this requirement, mesoprous alumina (MA) with a wide surface area and uniform pore size  was prepared, and a spongelike interlinked pore system was developed through a post-hydrolysis method



GSorb-810 is a Cu/ZnO  base adsorbent that widely used for removal of arsine, phosphine and reactive
sulfur from propylene containing streams. Due to its high surface area and ultra fine copper crystallite size, GSorb-810 is a ideal choice for the removal of arsine, phosphine, H2S and COS from process and product streams
