    KTA-2-type temperature arsenic removal

    First, Properties and Uses
    The purification catalyst chemical group into copper oxide - alumina. It is available in a new dearsenic room temperature or low (100 ℃ or less ) be used. It may be propylene, propane, FCC off-gas , a liquid hydrocarbon or alkyl arsine arsenic to be removed with the removal of these streams can be effectively sulfide (H2S, COS and mercaptans ) . The arsenic removal arsenic removal purification with high arsenic large capacity , high compressive strength . Hydrocarbons can be used in large-scale ethylene project , polypropylene unit , reformer materials such as Highland arsenic removal treatment process.


    Second, product quality standards
    Appearance black strips
    Specifications Φ5 mm
    Bulk density of 0.9 to 1.1 kg / l
    Radial crush strength ≥ 100 N / cm
    Arsenic penetration capacity ≥ 10%
    Chemical composition CuO, Al2O3


    Third, the normal process conditions
    Operating pressure atmospheric ~ 6.0 Mpa
    Operating temperature 10 ~ 100 ℃
    Liquid airspeed 1 ~ 6 h-1
    The gas space velocity of 1000 ~ 3000 h-1
    Bed height / column diameter > 4
    Imported water content <30 ppm
    Plateau material arsine content <3000 ppb
    After purification content ≤ 20 ppb arsine
    Plateau feed hydrogen sulfide content <5 ppm
    After the purification of hydrogen sulfide content ≤ 0.1 ppm


    Four industrial applications and application prospects
    KTA-2 -type temperature plateau material has been used for arsenic removal propylene domestic Yanshan , Zhenhai , Daqing, Jinxi and many medium-sized polypropylene unit arsine removal process . As the catalyst good arsenic removal , desulfurization performance , can replace imported dearsenic ensure the normal operation of a polymerization catalyst , improve product quality, have considerable economic benefits. The removal of arsenic can be used for liquid hydrocarbons , such as exhaust gas catalytic cracking feed dearsenifying plateau .


    Fifth, packaging and storage
    KTA-2 -type temperature arsenic removal using iron ( lined with plastic ) packaging , net weight 40 kg . This product must not be in contact with moisture and other chemicals . When transporting the need to prevent fall roll handling , collision . Airtight storage for three years does not affect use .
