Abstract

Process for obtaining binder-free absorbents characterized in that a molecular sieve zeolite is mixed in a finely powdered form with a finely particulate active aluminum oxide, hydration of the aluminum oxide being largely avoided during mixing; the resulting mixture is granulated in the presence of; water and the resulting granules are stored for at least 10 hours; and then they are dried and activated at a temperature between 200 and 500ºC.
