Olefin separation process |
| abstract |
An improved process for the separation of olefins from a hydrocarbon feed mixture comprising olefins and saturates which process uses a zeolite adsorbent to selectively adsorb the olefins. The improvement comprises employing a zeolite adsorbent produced by the steps of: contacting a precursor mass containing type X structured zeolite and amorphous material as a binder with an aqueous caustic solution to effect the addition of alkali metal cations to the crystalline structure; washing the mass with water to remove therefrom excess caustic solution; and, at least partially dehydrating said mass at dehydrating conditions thereby producing an adsorbent which has both increased capacity for olefins and decreased catalytic activity. |
