Olefin purification by adsorption of acetylenics and regeneration of adsorbent |
September 26, 2000 |
| Processes using heterogeneous adsorbents are disclosed for purification of relatively impure unsaturated hydrocarbons such as olefins, which are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a feed stream, containing acetylenic impurities, and, |
