The invention relates to a novel hybrid solid having a structural zeolite framework. CHA belongs to the ZIF family containing an inorganic network of Zn 2+ cation metal centers connected together by two organic ligands, 2-methylimidazolate, and a benzimidazolate. The invention also relates to the preparation and use of said adsorbent solid in a method for separating multi-branched paraffins included in a hydrocarbon feedstock containing linear paraffins, single-branched paraffins, and multi-branched paraffins having 5 to 7 carbon atoms per molecule, wherein said method includes placing said filler in contact with said adsorbent solid so as to produce at least a first stream enriched with multi-branched paraffins, and a second stream enriched with linear and single-branched paraffins. |
