Arsenic removal adsorbent

Its cost performance and Comprehensive Performance are obvious better than present domestic similar adsorbents.

Description:

The adsorbent is manufactured by a series unique process, which adopts American advanced technology, special carriers and additives. At room temperature it is mainly used for removal arsenide in liquid hydrocarbon feedstock, such as in naphtha, gasoline, diesel, kerosene, ethylene cracker feedstock.  It posses the characteristics of stable performance, strong adaptability and good mechanical strength, high precision of arsenic removal and large arsenide capacity. Its service life is longer min 3times than present domestic Copper sulfate – silicon aluminium sphere. Its cost performance and Comprehensive Performance are obvious better than present domestic using ambient-temperature oil arsenic removal adsorbents.
