Abstract

A process for the production of moulded bodies from dealuminated Y-zeolite (SiO.sub.2 /Al.sub.2 O.sub.3 >20) in which the microporous system of the zeolites and its characteristic adsorption properties are preserved and a binder whose slurry in water does not exceed a pH of 10 used in quantities of from 2 to 40%, based on the quantity of zeolite mass put into the process.
