LOWER REACTIVITY ADSORBENT AND HIGHER OXYGENATE CAPACITY FOR REMOVAL OF OXYGENATES FROM OLEFIN STREAMS

摘要

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.
