Lower reactivity adsorbent and higher oxygenate capacity for removal of oxygenates from olefin streams

---

Abstract

---

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.
