Air velocity of empty tower :U= 1.0m /s.OriginalIts adsorption performance mainly depends on several main material parameters and process parameters on it [8. Material parameters including carbon adsorption porosity, thickness of honeycomb structure and the content of carbon; process parameters including fluid flow rate and concentration of the adsorption properties of adsorption, can adsorption depends on the carbon structure and adsorption properties of features such as molecular weight). The curve is one of the main performance characterization of adsorption, adsorption is the adsorbate concentration ratio before and after the change over time of a function [9 '. This ratio is 0.95, the amount of adsorption properties of adsorption is called penetration capacity. Penetration capacity depending on the fluid flow rate, the concentration of the adsorbate and honeycomb carbon component content  activated carbon suppliers canada 

Using small activated carbon fixed bed adsorption gas phase dioxin test bench, a typical activated carbon adsorption dioxin factors affecting the experimental study, discusses the types of dioxin adsorption activated carbon and activated carbon fixed bed adsorption gas phase characteristics of dioxins, and discusses the adsorption temperature and adsorption time of activated carbon adsorption of dioxins.The results showed that the specific surface area and micropore volume of activated carbon had weak correlation with the adsorption efficiency of dioxins.

The mesopore volume of activated carbon is an important factor to determine the adsorption capacity of dioxins. The surface area of the pore size between 2 nm and 20nm plays a key role in the adsorption of dioxins.The higher the adsorption temperature, the lower the adsorption efficiency of activated carbon.The longer the adsorption time, the lower the adsorption efficiency of activated carbon.There is no selective adsorption of gaseous dioxins in activated carbon fixed bed. dxd carbon
