The basic principle of treating industrial organic waste gas by adsorption

Because there is not a solid surface balance and unsaturated molecular attraction or chemical bonding force, so when the solid surface in contact with the gas, can attract the gas molecules, the concentration and remained in the solid surface, this phenomenon is known as adsorption. The adsorption capacity of the solid surface is used to make the exhaust gas contact with the porous solid substance on the large surface, and the pollutants in the exhaust gas are adsorbed on the solid surface so as to be separated from the gas mixture to achieve the purpose of purification.

According to the different gas molecules and solid surface molecular interactions, adsorption can be divided into physical adsorption and chemical adsorption, the former is the intermolecular force, the latter is the formation of chemical bond between molecules of the results, we use the physical adsorption.
