In the study of the removal of VOCs, SO2, NH3 and other multi-component pollutants in the air, physical adsorption method has a wide range of application prospects and research value because of its advantages of high efficiency, low consumption, low concentration and no secondary pollution. And the penetrating curve analysis method is the classic method in this field because it is close to the actual application condition. Through this method, accurate information such as the amount of adsorbent, adsorption capacity, adsorption rate, purification effect, activation conditions, filter element life and so on can be given.

Different types of adsorbents for different fields of application, such as activated carbon has strong adsorption of VOCs gas, can be used for organic steam recovery and air purification; Molecular sieve, MOF and other materials have significant selective adsorption of specific gas, can be used for air separation, purification and other mixed gas separation fields.

Fixed bed reactor is widely used in industrial catalysis, high purity gas preparation, tail gas treatment and other fields. Physical adsorption on a fixed bed is the complete or selective absorption of multi-component adsorbent gas by adsorbent to achieve its industrial application. A complete understanding of the adsorption and desorption processes occurring on a fixed bed is the key to mixed gas adsorption and separation, industrial catalysis and other industrial applications. The penetration curve of a fixed bed reactor with a reasonable proportion of the separation process is the basis of the design and operation of the fixed bed adsorption process.

Test principle

The penetration column is equipped with granular adsorbent, piled into a bed with a certain height, the bed is stationary, the mixed gas through the adsorbent inlet into, adsorbent adsorption, and then outflow from the outlet, through the determination of the change of the concentration of each component of the export gas with time that is the penetration curve, To measure the penetration time of components in addition to carrier gas and the selective adsorption amount of each component of the gas mixture.

 Major function

A. Use the adsorption penetration curve analyzer with its own thermal conductivity detector to determine the following different experimental conditions of the two-component adsorption penetration curve: different adsorbent, different temperature, different pressure, different bed thickness, different gas concentration, different penetration flow;

B. Connected chromatography or mass spectrometry -- Complete three or more components of the multi-component competitive adsorption, selective adsorption and displacement adsorption tests.

C. Realize the adsorption test of TVOC, SO2, NH3 and other pollution gases with ppm concentration of adsorbent, especially suitable for the evaluation of adsorption performance of trace pollution gases in indoor, car and other environment and the determination of adsorption parameters.
