Iron oxide desulfurizers are roughly divided into the following types according to different raw materials: the desulfurizers are made of pure hydrated iron oxide plus forming agent and pore-forming agent. This iron oxide desulfurizer uses pure hydrated iron oxide. However, the production process of pure hydrated iron oxide is complicated and cumbersome. Therefore, the desulfurization agent hydrated iron oxide produced by this method has high content and high cost. At present, there are not many manufacturers using this method to produce desulfurizer in the country.

A desulfurizer made of ferrous sulfate and alkaline substances plus a forming agent and a pore-forming agent. Due to the low price of raw materials, there are many manufacturers using this method to produce desulfurizers, but the hydration oxidation Iron content is lower. The desulfurizer made of natural iron ore is limited by the origin of the raw material, and can be divided into powdery and cylindrical according to different shapes. Iron oxide desulfurizers can be divided into these categories, I believe everyone has a certain understanding.
