There are several kinds of desulfurizer

According to the different raw materials can be roughly divided into the following: first, the use of pure hydrated iron oxide plus molding agent and pore forming agent made of desulfurizer. This kind of iron oxide desulfurizer uses 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 also high. At present, there are not many desulfurizer manufacturers using this method in China. (for example, t703 of Hubei Institute of chemistry, xyf-2 of Xiangyu chemical, and Yuxin 2 of Yuxin activated carbon plant are produced by this method.) 2、 The desulfurizer is made of ferrous sulfate, alkaline substance, forming agent and pore forming agent. Due to the low price of raw materials, there are many manufacturers using this method to produce desulfurizer, but the content of hydrated iron oxide is low. 3、 Desulfurizer made from natural iron ore. The desulfurizer produced by this method is limited by the place of origin of raw materials. At present, many manufacturers in Shanxi produce desulfurizer by this method. According to the shape, it can be divided into powder and cylinder.
