Abstract
An automated experimental test facility, intended specifically for qualification of the krypton and xenonadsorption properties of activated carbon samples, was designed and constructed. The experimentalapparatus was designed to allow an on-line control of the main physical parameters influencing greatlythe adsorption property of activated carbon. The measurement of the adsorption coefficient, based uponthe elution curve method, can be performed with a precision better than 5% at gas pressure values rangingfrom atmospheric pressure up to 9 bar and bed temperature from 0 up to 80◦C. The carrier gas flow ratecan be varied from 40 up to 4000 N cm3min−1allowing measurement of dynamic adsorption coefficientwith face velocities from 0.3 up to 923 cm min−1 depending on the gas pressure and the test cell beingused. The moisture content of the activated carbon can be precisely controlled during measurement,through the relative humidity of the carrier gas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
