Adsorption Capacity

Two types of adsorption adsorption in liquid phase and gas phase adsorption, liquid-phase adsorption capacity to evaluate the adsorption isotherms, gas adsorption capability evaluation of solvent vapor adsorption.

Adsorption adsorption isotherms indicate a temperature adsorbed material in the system of partial pressure or the relationship between concentration and absorption, that is, when kept at constant temperature, measured equilibrium sorption capacity and relationship between partial pressure or concentration. With residual concentrations as the horizontal axis, the adsorption capacity of activated carbon form quality can draw a curve for the vertical axis.

When maintaining partial pressure or concentration does not change, measured equilibrium relationship between volume and temperature, draw a curve, namely, adsorption Isobar. Because few in the industrial component adsorption isothermal condition, so most important and commonly used adsorption isotherms.

Solvent steam gas adsorption volume said gas phase adsorption performance, available particles activated carbon of carbon tetrachloride adsorption rate of determination for cases, in provides of test conditions Xia, that provides of carbon layer height, and air than speed, and adsorption temperature, and determination tube cut area, and carbon tetrachloride steam gas concentration of conditions Xia, holding contains must carbon tetrachloride steam gas concentration of mixed air flow constantly to through activity carbon, dang reached adsorption saturated Shi, activated carbon sample by adsorption of carbon tetrachloride of quality and sample quality of percentage as carbon tetrachloride of adsorption rate.

Application of activated carbon adsorption capacity, with actual specimens of the best activated carbons, operational conditions, specific evaluation tests.
