Shape; is white or light yellow spherical fine powder, density 5.47g/cm3, melting point 1800 ℃, insoluble in water, soluble in acid, alkali, chloride and ammonia. Made of zinc oxide desulfurization agent with a large surface area, and the penetration of high sulfur capacity, high mechanical strength, accumulation of a large gap, small pressure drop characteristics 
 Widely used in synthetic ammonia, methanol and hydrogen and other industrial raw materials, gas, oil deep sulfur removal process. At a certain temperature and pressure the small amount of hydrogen sulfide gas can, effectively reducing the concentration of organic sulfur
