CORE-SHELL COMPOSITE ABSORBENT FOR USE IN PSA PRE-CLEANERS AND CYCLIC ABSORPTION PROCESSES

The present invention relates generally to an attrition resistant core-in-shell composite adsorbent comprising at least a zeolite-containing CO2 removal adsorbent and a binder on an inert dense core. The attrition resistant core-in-shell composite adsorbent has an attrition loss of less than about 2...

More Information
Summary:The present invention relates generally to an attrition resistant core-in-shell composite adsorbent comprising at least a zeolite-containing CO2 removal adsorbent and a binder on an inert dense core. The attrition resistant core-in-shell composite adsorbent has an attrition loss of less than about 2 wt %. The core-in-shell composite adsorbent is preferably used in a multi-layered adsorption system in a cyclic adsorption process, preferably used in a PSA prepurification process prior to cryogenic air separation.
