KTA-1-type temperature arsenic removal

First, Properties and Uses
The chemical composition of the purification catalyst is copper oxide - aluminum oxide . It is available in a new dearsenic room temperature or low (100 ℃ or less ) be used. It can be expected plateau naphtha , liquid hydrocarbon and an alkyl arsine arsenic to be removed , which can be removed while the reactive sulfur ( hydrogen sulfide , mercaptans ) . The arsenic removal arsenic removal capacity, high compressive strength, can be applied to ethylene , naphtha reforming unit are to be expected in Highland arsenic removal processes. Highland feed water content and higher sulfur content will affect the arsenic removal .
 
Second, product quality standards

Plateau material ≤ 400 ppb of arsenic
Arsenic tolerance depending on conditions of work and provides
 
Fourth, industrial application and application prospects
KTA-1 -type temperature de- arsenic has been used a number of domestic refinery naphtha feed to plateau arsenic removal process can be refined to meet the restructuring process requirements , is a promising new arsenic removal .
 
Fifth, packaging and storage
KTA-1 -type temperature arsenic removal using iron ( lined with plastic ) packaging , net weight 35 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 3-5 years does not affect use .
