Applicant has developed an improved adsorbent useful in removing contaminan ts from various hydrocarbon streams. The adsorbent contains a zeolite, an alumi na and a metal component. The metal component (M add) is present in an amount at leas t 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 adsorbe nt comprising zeolite X, alumina and sodium is used to purify an ethylene stream in order to remove CO2, H2S, methanol, and other S- and O- containing compounds. |
