Abstract
The present invention is directed to a process for removing impurities from hydrocarbon streams, preferably light ends, such as propylene and ethylene, which is preferably in the liquid phase, by contacting the hydrocarbon stream containing an initial amount of an impurity with a chemical adsorbent which is composed of a modified alumina having a surface area within the range of about 10 m.sup.2 /g to about 300 m.sup.2 /g and a pore volume within the range of about 0.1 mL/g to about 1 mL/g under contacting conditions effective to result in a purified hydrocarbon stream containing a reduced amount of impurities, i.e., less than about 0.5% relative to the initial amount of the acid impurity present in the hydrocarbon stream, and more preferably within the 10 ppb range.
