T-302 zinc oxide desulfurization adsorbent

basic information

Numbers:

cp2003

Detailed

T-302 zinc oxide desulfurization adsorbent is composed of active zinc oxide, manganese oxide and magnesium oxide. Active zinc oxide is main component. It has the ability of good adsorption of hydrogen sulfide and converting the simple organic sulfur compounds. In addition, it still has good desulfurization activity at room temperature and the desulfurization rate can reach 99.5%.
The product which is mainly used in synthesis ammonia plant of semi-water-gas as raw materials, removes the small amount of H2S and "reactive" organic sulfur in feed gas in low temperature shift stove to protect the low-temperature shift catalyst.
It is also used for desulfurization from natural gas, oil gas, coke-oven gas and rich gas of refinery coking which is hydrogenated and of coking gas refinery.
