Abstract
The present invention concerns a zeolitic adsorbent agglomerate comprising at least one zeolite of faujasite type comprising barium and/or potassium, of porosity between 25% and 45%, and having a standard deviation σ of crystal size distribution in said agglomerate of less than 0.30 μm. The invention also concerns the use of the zeolitic adsorbent agglomerate for the separation of hydrocarbon mixtures, and the process for separating hydrocarbon mixtures using said zeolitic adsorbent agglomerate.
