Conclusions
-
1.
A study has been made of the isotherms for krypton and xenon adsorption on activated charcoals with various micropore structures, working over wide intervals of adsorption-space packing and temperature, with inclusion of the critical points.
-
2.
Degrees of adsorption-space packing have been calculated for each of the experiments. The results obtained support the theory of bulk micropore filling, showing inert-gas adsorption to be highest on the charcoal having the lowest value of the B parameter in the adsorption-isotherm equation.
-
3.
The fact that the adsorption isosteres were linear at all temperatures and adsorptions can be considered as an indication that passage from vapor to gaseous adsorption occurs continuously.
