Arsine is known as one of the most poisons to downstream catalyst in hydrocarbon processing, which is present in ppb level in propylene stream can poisons the downstream precious metal catalyst in polypropylene plants. Also Natural gas frequently contains arsine and other arsenic compounds that some of the type are not effectively removed with a traditional adsorbent. SINOCATA offers serial arsine adsobents to meet the update requirements. The choice of the specific adsorbent portfolio depends on the feed stream characteristics, type of impurity to be removed, and the process conditions such as the pressure, temperature etc. Arsine can be removed at ppb levels by using SINOCATA’s Arsine Removal catalyst.
Application
T-AS-1, an Cu/Zn catalyst, Dia.2×3-10mm, Cylindrical extrudae, Bulk density: 850 – 950KG/m3, which is widely used for arsine/ phosphine removing from propylene, ethylene, butylene and other chemical materials. Since being developed, it has been successfully being applied in many industrial units. T-AS-1 has outstanding performance, the product has high crushing strength, extraordinarily high arsine pick-up capacity and can work at very low working temperature.
T-AS-11, an Cu/Zn catalyst, Dia.5x5mm, Tablet, Bulk density: 1150 – 1350KG/m3, which is widely used for arsine/ phosphine removing from propylene, ethylene, butylene and other chemical materials. Since being developed, it has been successfully being applied in many industrial units. T-AS-11 has outstanding performance, the product has high crushing strength, extraordinarily high arsine pick-up capacity and can work at very low working temperature.
T-AS-2, Dia.2.5mm, Trilobe extrudate, Bulk density: 600 – 800KG/m3, take Cu as main active component which is widely used for arsine/ phosphine removing from liquid and vapor phase hydrocarbon streams to naphtha, such as gasoline, diesel, kerosene, naphtha, ethylene cracker feed purification.
T-AS-3, Dia.3-5mm, Spheres, Bulk density: 700 – 900KG/m3, which is widely used for arsine/ phosphine removing from liquid and vapor phase hydrocarbon streams to naphtha, such as gasoline, diesel, kerosene, naphtha, ethylene cracker feed purification.
T-AS-33, Dia.4mm, Cylindrical extrudate, Bulk density: 600 – 800KG/m3, which is used for arsine/ phosphine removing from liquid and vapor phase hydrocarbon streams to naphtha, such as gasoline, diesel, kerosene, naphtha, ethylene cracker feed purification.
T-AS-4, 3-5mm, Spheres, Bulk density: 650 – 750KG/m3, which is used for arsine/ phosphine removing from liquid and vapor phase hydrocarbon streams to naphtha density.
