Zinc Oxide Desulfurizer Adsorbent Catalyst in Oil Refinery

Product Description

Zinc oxide desulfurizer is mainly made of active zinc oxide, adding appropriate amount of additives, and adopting special processing technology to refine it. It has the characteristics of wide service temperature, high purification degree, long life (high sulfur capacity), high strength water vapor resistance.

Application of Zinc Oxide Desulfurizer
Zinc oxide desulfurizer is mainly used for the purification and refining of raw materials such as gas, oil, hydrocarbon and synthesis gas, to remove hydrogen sulfide, and to absorb small molecular organic sulfides such as CS2, COS, mercaptans, etc. The hydrogen sulfide content of various raw materials purified by desulfurizers can reach less than 0.1PPm, and the saturated sulfur capacity can reach 35%. According to temperature, it can be divided into normal temperature, medium temperature, high temperature and low temperature zinc oxide desulfurizer.
The desulfurization reaction is a chemical absorption process, and the chemical reaction equation is as follows:
ZnO+H2S→ZnS+H2O
