Dry degree of activated carbon
The moisture content of raw materials. The moisture content of the sawdust affects the rate of chemical penetration into the sawdust particles, thus affecting the impregnation time. When the moisture content of sawdust is more than 30%, the impregnation time is more than 8h. Generally, the moisture content of sawdust should not exceed 5%. According to the different production technology, the moisture content of sawdust has different specific indexes.
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 contentcoconut shell activated carbon pellets
Factors such as [10. For honeycomb activated carbon, the wall thickness is a very important parameter, by changing the wall thickness to improve its adsorption efficiency. Under the same porosity, thickness increases, the honeycomb carbon content per unit volume also will increase, which can improve the adsorption capacity. This is because the wall thickness increases, the fluid channel in the cellular cross-sectional area reduced, so the real surface or volume flow rate will increase. At the same time, the contact between...
