specific Embodiment approach

[0059] While the following is described in connection with specific embodiments, it should be understood that this description is intended to illustrate, and not to limit, the scope of the foregoing description and appended claims.

[0060]A first embodiment of the invention is a process for removing pollutants from a stream comprising contacting an olefin-containing olefin stream with a sorbent in a pollutant removal zone, wherein the sorbent comprises copper, copper oxide, cuprous oxide and halides; selectively removing one or more contaminants selected from the group consisting of mercury, arsenic, phosphine, and sulfur compounds from an olefin stream; and selectively converting the olefin stream to The acetylenic compound is converted to an olefin, wherein the acetylenic conversion zone receives hydrogen. An embodiment of the invention is one, any or all of the previous embodiments in this paragraph up through the first embodiment in this paragraph, wherein the sorbent fur...

Abstract

Copper sorbents which are resistant to the reduction by hydrogen are used as a guard bed for an acetylene conversion zone. The adsorbents include cuprous oxide, cupric oxide, copper metal, and a halide and are pre-reduced prior to be loaded into the guard bed. The sorbents can remove contaminants that would poison selective hydrogenation catalysts used for a selectively hydrogenating acetylenic compounds in an olefin stream. The sorbents may also selectively hydrogenate the acetylenic compounds.

Description

[0001] priority statement [0002] This application claims priority to US Application No. 62 / 253412, filed November 10, 2015, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates generally to alkyne converters, more specifically to guard beds for alkyne converters, and even more particularly to novel sorbents configured to remove contaminants from alkyne converter feed streams. Background technique [0004] Olefins, including ethylene and propylene, can be converted on a large scale into a variety of intermediates and end products, such as polymeric materials. Commercial production of olefins is primarily accomplished by thermal cracking of hydrocarbons. Unfortunately, due to the very high temperatures involved, these commercial olefin production processes also produce significant amounts of undesired acetylenic (alkyne) impurities, such as acetylene, methylacetylene, and C4 alkynes, which conta...
