active zinc oxide (chemical method) ZnO ISO9001

1 ton Active zinc oxide can be an alternative of 1.5 tons indirect zinc oxide. We produce the active zinc oxidefor removing sulfides. It has the characteristics of large specific surface area, low heavy metal content, high sulfur tolerance, good sulfur removal capacity, big bulk destiny, small layer pressure drop, fine resistance of water and better adoptability. It can be widely used for (1)Removing of sulfides from synthetic gases, natural gas, oil field gas, shift gases and liquid hydrocarbon; (2)Making the Methyl alcohol and petrochemical industry raw material oil gas has depth desulphurization purification process; (3)Reducing the gas in hydrogen sulfide and the organic sulfides density effectively under certain temperature and the pressure.
