PSA process using an adsorbent which has an intrinsic resistance that is favourable to the adsorption kinetics

摘要

A new adsorbent for separating gases contains particles of a zeolite with an Si/Al ratio less than or equal to 5, chosen fro or A type zeolites. The zeolite has a kinetic coefficient ak 0.5 s<-1> and an intrinsic resistance alpha such 0.10 alpha 2. An Independent claim is also included for a PSA (pressure swing adsorption) process for separating gas components of differ absorbability, using the zeolite (which may additionally be of the Y type).
