Activated carbon desulfurization adsorbent for natural gas, refinery gas, liquid petroleum gas, catalytic gasoline and light oil
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.

Alkali metal compounds, is mainly used in desulfurization for natural gas, refinery gas, liquid petroleum gas, catalytic gasoline and light oil. The product can replace regular liquid alkaline cleaning process without emission of waste lye, which can eliminate the secondary pollution caused by treating waste alkali. The product has good effect for desulfurization.
With the injection of special additives, it can run stably in a long-period with high activity .The product has been used successfully in multi-sets industrial plants in the world.
