A commercial version of 8% Na2 O promoted alumina has {HEAD ~ an HCl capacity} of 12.9% and 1,3 butadiene reactivity of 5.7% By gradually increasing the amount of water pre loaded on the adsorbent, a steady increase in HCl adsorption capacity and a steady decrease in 1,3 butadiene reactivity was observed with a water pre loading of from about 5 to about 11 weight percent of {TAIL ~ the adsorbent} relative to the adsorbent on an essentially water free basis
