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

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 .
