An improved adsorbent useful in removing contaminants from various hydrocarbon streams comprises a zeolite, an alumina and an added metal component provided in the adsorbent by initially contacting primarily the zeolite with the added metal. In a specific application, an adsorbent comprising sodium-impregnated zeolite Y and alumina is used to purify an ethylene stream in order to remove CO2, H2S, methanol, and other S- and O-containing compounds.

1. A solid adsorbent for purifying hydrocarbon streams comprising an alumina component, a zeolite component and a added metal component, the added metal component being present in an amount of from about 0.0075 to 0.0135 moles of the metal as the oxide per 100 g of adsorbent and where the alumina is
1. A solid adsorbent for purifying hydrocarbon streams comprising an alumina component, a zeolite component and a added metal component, the added metal component being present in an amount of from about 0.0075 to 0.0135 moles of the metal as the oxide per 100 g of adsorbent and where the alumina is present in an amount from about 40 to about 90 wt. % of the adsorbent. 2. The adsorbent of claim 1 where the zeolite is selected from the group consisting of zeolite X, zeolite Y, zeolite A, ZSM-5, zeolite beta and mixtures thereof. 3. The adsorbent of claim 1 where the added metal component is an alkali metal selected from the group consisting of sodium, potassium, lithium, rubidium, cesium and mixtures thereof. 4. The adsorbent of claim 3 wherein the added metal component is sodium. 5. The adsorbent of claim 1 wherein the added metal component is initially added primarily to the zeolite such that the added metal is present in the zeolite component in amounts greater than if the same amount of initial metal was added to a mixture of the zeolite and alumina. 6. The adsorbent of claim 5 in the form of a solid shape comprising a mixture of zeolite and alumina particles. 7. A solid adsorbent for purifying hydrocarbon streams comprising an alumina component, a zeolite component and an added metal component, the added metal component being initially added primarily to the zeolite such that the added metal is present in the zeolite component in amounts greater than if the same amount of initial metal was added to a mixture of the zeolite and the alumina. 8. The adsorbent of claim 7 where the zeolite is selected from the group consisting of zeolite X, zeolite Y, zeolite A, ZSM-5, zeolite beta and mixtures thereof. 9. The adsorbent of claim 8 where the zeolite is zeolite Y. 10. The adsorbent of claim 7 where the added metal component is an alkali metal selected from the group consisting of sodium, potassium, lithium, rubidium, cesium and mixtures thereof. 11. The adsorbent of claim 10 where the metal component is sodium. 12. The adsorbent of claim 7 wherein the added metal component is present in an amount of from about 0.0075 to 0.05 moles of the metal as the oxide per 100 g of adsorbent. 13. A process for preparing a solid adsorbent for purifying hydrocarbon streams comprising an alumina component, a zeolite component and an added metal component where the alumina is present in an amount from about 40 to about 90 wt. % of the adsorbent; the process comprising combining a zeolite component with an added metal component precursor to form an impregnated zeolite, combining the impregnated zeolite and alumina to form a shaped article and activating the article at activation conditions to give the solid adsorbent. 14. The process of claim 13 where the zeolite component is selected from the group consisting of zeolite X, zeolite Y, zeolite A, ZSM-5, zeolite beta and mixtures thereof. 15. The process of claim 13 where the added metal component precursor is selected from a carboxylate, carbonate, aluminate and hydroxide compound of the metal component. 16. The process of claim 13 where the added metal component is an alkali metal. 17. The process of claim 13 comprising curing said shaped article prior to activation, wherein said curing takes place at a temperature of about ambient to about 200° C. and a time of about 5 minutes to about 25 hours. 18. The process of claim 13 where the activation conditions include a temperature of about 275° C. to about 600° C. and a time of about 5 to about 70 minutes. 19. A method of removing contaminants from a hydrocarbon stream comprising contacting the hydrocarbon stream with the adsorbent of claim 1. 20. A method of removing contaminants from a hydrocarbon stream comprising contacting the hydrocarbon stream with the adsorbent of claim 7.
