ABSTRACT:
The highly lithium exchanged forms of zeolite X, particularly the low silica forms of zeolite X which contain more than ninety equivalent percent lithium cations, have been found to exhibit extraordinary capacities and selectivities for nitrogen adsorption. Such adsorbents are to a surprising degree effective in separating nitrogen from gas streams such as air and mixtures of nitrogen with less polar substances such as hydrogen, argon and methane. Pressure swing adsorption separation process are well suited to take advantage of the exceptional properties of these absorbents.
