How many desulfurizers are there

According to different raw materials, it can be roughly divided into the following types: 1. The desulfurizer is made of pure hydrated iron oxide, molding agent and pore-forming agent. This kind of iron oxide desulfurizer adopts pure hydrated iron oxide, and the production process of pure hydrated iron oxide is extremely complicated and cumbersome. Therefore, the desulfurizer produced by this method has high hydrated iron oxide content and high cost. At present, there are not many manufacturers using this method to produce desulfurizers in China. (For example, T703 of Hubei Chemical Research Institute, XYF-2 of Xiangyu Chemical Industry and Yuxin No.2 of Yuxin Activated Carbon Factory are produced by this method. (2) desulfurizer 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 desulfurizers, but the content of hydrated iron oxide is low. 3. Desulfurizer prepared from natural iron ore. The desulfurizer produced by this method is limited by the origin of raw materials, so there are more desulfurizers produced by this method in Shanxi. According to different shapes, it can be divided into powder and cylinder.
