According to the different raw materials, it can be roughly divided into the following categories: 1. Desulfurizer made of pure hydrated iron oxide plus molding agent and pore forming agent. This kind of desulfurizer is pure hydrated iron oxide, and the production process of pure hydrated iron oxide is extremely complex and cumbersome. Therefore, the content of hydrated iron oxide produced by this method is high and the cost is high. At present, there are not many manufacturers using this method to produce desulfurizer in China. (for example, t703 of Hubei Chemical Research Institute, xyf-2 type of Xiangyu chemical industry and Yuxin No. 2 of Yuxin activated carbon plant are produced by this method.) 2、 The desulfurizer is made of ferrous sulfate, basic material, molding agent and pore forming agent. Because of the low cost of raw materials, there are many desulfurizers produced by this method, but the content of hydrated iron oxide is low. 3、 Desulfurizer made of natural iron ore. Due to the limitation of the origin of raw materials, the desulfurizer produced by this method is more in Shanxi factories at present. According to different shapes, it can be divided into powder and cylindrical shape.
