Abstract
The invention relates to a process for purification of olefinic feedstocks using an adsorbent comprising a 12 MR-type zeolite, in which the zeolite content of said adsorbent is between 93% by weight and 100% by weight, and the binder content of said adsorbent is between 0 and 7% by weight, in which said zeolite contains silicon and an element T that is selected from the group that consists of aluminum, boron, gallium and iron, and in which the Si/T atomic ratio is less than 20.
