According to the different raw materials, it can be divided into the following categories: first, the desulfurizer made by using pure hydrated iron oxide plus forming agent and pore making agent. This kind of desulfurizer uses pure iron oxide hydrate, and the production process of pure iron oxide hydrate is extremely complex and complicated. Therefore, the desulfurizer produced by this method has high content and high cost. At present, there are not many manufacturers in the country that use this method to produce desulfurizer( For example, t703 of Hubei Institute of chemistry, xyf-2 of Xiangyu chemical industry and Yuxin No. 2 of Yuxin activated carbon plant are produced by this method.) 2、 The desulfurizer is made by ferrous sulfate and alkaline material plus forming agent and pore making agent. Because of the low price of raw materials, there are many desulfurizer manufacturers using this method, but the content of hydrated iron oxide is low. 3、 Desulfurizer made from natural iron ore. Because of the limitation of raw material origin, there are many desulfurizer produced by this method in Shanxi. According to the shape, it can be divided into powder and cylinder.
