The present invention relates to spherical agglomerates based on zeolite (s) and clay (s), having controlled size and morphology, in particular a size of less than or equal to 600 μm, very good sphericity, high content of zeolitic material, and their production process.These agglomerates are particularly suitable for uses in gaseous and/or liquid-phase adsorption processes.本發明係關於具有受控尺寸及形態(尤其小於或等於600 μm之尺寸及極佳球型)、高沸石材料含量的以沸石及黏土為主之球型黏聚物及其製造方法。該等黏聚物尤其適合用於氣相及/或液相吸附製程中。
