Abstract
The present invention relates to binder-free molecular sieve zeolite granules of lithium zeolite A and lithium zeolite X, a process for preparing these molecular sieve zeolite granules and their use for preparing nitrogen or oxygen from air by pressure swing adsorption.
Claims6
Molecular sieve zeolite granules, characterized in that said granules consist essentially of a mixture of zeolites of Li zeolite A and Li zeolite X, said granules containing 10 to 35 wt. % of Li zeolite A and 65 to 90 wt. % of Li zeolite X wherein the Li zeolite A was obtained by the conversion of a silicate binder.
