| titleOfInvention | Treatment of adsorbent to enhance adsorbent capacity for acetylenic compounds |
| abstract | Processes using heterogeneous adsorbents are disclosed for purification of olefin streams, such as are produced by thermal cracking of hydrocarbons, to obtain a feedstock suitable for formation of olefin polymers. These purification processes comprises: providing an impure gaseous mixture; passing the impure mixture through a bed of regenerated adsorbent which is free of a substantial amount of carbon monoxide; effecting, in the presence of an essentially dihydrogen-free atmosphere within the bed, selective adsorption of the contained acetylenic impurities with the adsorbent until levels of the acetylenic impurities in the effluent mixture increase to a limiting level in a range downward from about 1 parts per million by volume; and thereafter regenerating the resulting bed of adsorbent in the presence of a reducing gas comprising dihydrogen which reducing gas is free of a substantial amount of carbon monoxide. |
