Applicant has developed an improved adsorbent useful in removing contaminants from various hydrocarbon streams. The adsorbent contains a zeolite, an alumina and a metal component. The metal component (Madd) is present in an amount at least 10 mole % the stoichiometric amount of metal (M) (expressed as the oxide) needed to balance the negative charge of the zeolite lattice. In a specific application an adsorbent comprising zeolite X, alumina and sodium is used to purify an ethylene stream in order to remove CO<HIL><PDAT>2</SB><PDAT>, H<HIL><PDAT>2</SB><PDAT>S, methanol, and other S- and O- containing compounds.</PTEXT>
