Lower Reactivity Adsorbent and Higher Oxygenate Capacity for Removal of Oxygenates from Olefin Streams

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-...

Zusammenfassung: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.
