GSorb-800 series

The polymerization reactions to make polypropylene occur over high activity Ziegler-Natta type catalysts. In order to provide the best catalytic activity of these catalysts, the feed olefin and any other hydrocarbon streams, such as co-monomer streams, must be free of contaminantes that can bond to the transitional metal groups on the catalyst, thus deactivating the catalyst. the metalloucenes are exteremly sensitivity to levels in the parts per billion (ppb) level range. most polypropylene manufacturers specify extremely low levels of arsine and phosphine contamination in their propylene supplies with specifications set any were from 5 to 50 ppb of either of these impurities. the same issues are peresent in the manufacture of various other polymers, including polyethylene, polystyrene and various clastomers. GAHARCERAM  provide GSorb-800 series for effective removal of arsine, phosphine, cabonyl sulfide and hydrogen sulfide up to ppb levels. These series of adsorbent can be used in purification of various streams such as propylene, ethylene and other hydrocarbon streams.

GSorb-800 series adsorbents 

GSorb-800

An ideal adsorbent should have appropriate surface area and uniformly accessible pores,  physical and/or chemical stability. To meet this requirements, we provide a mesoprous alumina with a wide surface area and uniform pore size and a spongelike interlinked pore system to achieve a unique performance.


GSorb-810

GSorb-810 is one of the metal oxide active adsorbents that can be adsorb arsenic, phosphine and reactive sulfur compounds by chemisorption. Due to its high surface area and ultra fine copper crystals, it can be an ideal choice for removing H2S, COS, AsH3 and PH3 from various streams. One of the unique features of this product is  high adsorption capacityThat makes it economically attractive.


GSorb-820

Lead oxide active phase does not promote polymer formation, so it is especially suitable for streams containing acetylenes or dienes, which have a tendency to foul other types of guard bed materials. GSorb-820 is applicable for purification of hydrogen-rich gases, where other metal oxides (CuO or ZnO, etc) cannot be used due to their reactivity toward the hydrogen content in the gas stream.


GSorb-830

GSorb-830 is a Cu-Zn based adsorbent that widely used for removal of arsine, phosphine and reactive sulfur (H2S, COS) from liquid and gas hydrocarbon streams. The outstanding performance of GSorb-830 such as high crushing strength and extraordinarily high capacity, made it an ideal adsorbent for purification of polymerization feed streams such as propylene, etc.

Choosing appropriate adsorbent for each process depends on several parameters including operating temperature,  pressure, type and quantity of present contaminates in the feed, etc. Contact us for more information and technical support
