Abstract
An improved adsorbent for ozone comprises a crystalline aluminosilicate in which at least 90% of the exchangeable cation content is in the acid form and further which contains between 0.5 and 20 wt % of one or more adsorbed components which are non-reactive with ozone. Preferably the adsorbed component is water, and the total non-framework metal content expressed as metal oxide is less than 0.4 mole %.
