Abstract
The present invention concerns an adsorbent comprising at least one zeolite selected from a zeolite of the 12 MR, 10 MR and 8 MR type and at least one binder comprising a clay with a Si/Al weight ratio of more than 2. It also concerns its preparation process and its use in a process for purifying a hydrocarbon feed comprising unsaturated molecules and at least one impurity comprising at least one heteroatom of the O, S or N type.
