description

Abstract Isothermal and isobaric adsorptions of p -xylene and m -xylene on NaY, KY, and BaY are studied by thermogravimetry between 25°C and 400°C, and 10 Pa and 1014 Pa. At low filling BaY shows a stronger affinity for xylenes than the other zeolites. At high temperature and low pressure its adsorption capacity is greater than those of NaY and KY. These two zeolites have a similar behavior and adsorb more m -xylene than p -xylene. At low temperature and high pressure KY adsorbs p -xylene like NaY and m -xylene like BaY, and, unlike NaY, the adsorption capacities of KY and BaY are higher for p -xylene than for m -xylene. The substitution of K + or Ba 2+ for Na + decreases the adsorption capacity of α-cages.
