This invention pertains to the use of a catalyst that contains at least one dioctahedral phyllosilicate 2:1, which is preferably synthesized in a fluoride medium in the presence of HF acid and/or another source of fluoride anions, whose reticulate distance is equal to at least 20×10−10 m (2 nm) and which includes pillars that are based on at least one oxide from the elements of groups IVB, VB, VIB, VIII, IB, IIB, IIA, IVA, or any combination of these oxides, and preferably selected from the group composed of SiO2, Al2O3, TiO2, ZrO2, and V2O5, or any combination of the latter and at least one element from group VIII, in a process for isomerization of a feedstock that contains mainly normal paraffins that carry 5 to 10 carbon atoms per molecule.
A catalyst that contains at least one dioctahedral phyllosilicate 2:1 whose reticulate distance is equal to at least 26.5×10−10 m and which includes pillars based on at least one oxide from the elements of groups IVB, VB, VIB, VIII, IB, IIB, IIA, IVA, or any combination of these oxides, and at least one element from group VIII wherein the phyllosilicate was synthesized in a fluoride medium in the presence at least one of HF acid and another source of fluoride anions, resulting in the incorporation of F in the catalyst.
A catalyst that contains at least one dioctahedral phyllosilicate 2:1 whose reticulate distance is equal to at least 20×10−10 and that is less than or equal to 60×10−10 m, and which includes pillars based on at least one oxide from the elements of groups IVB, VB, VIB, VIII, IB, IIB, IIA, IVA, or any combination of these oxides, and at least one element from group VIII wherein the phyllosilicate was synthesized in a fluoride medium in the presence at least one of HF acid and another source of fluoride anions, resulting in the incorporation of F in the catalyst.
A catalyst that contains at least one dioctahedral phyllosilicate 2:1 whose reticulate distance is equal to at least 26.5×10−10 m and which includes pillars based on at least one oxide from the elements of groups IVB, VB, VIB, VIII, IB, IIB, IIA, IVA, or any combination of these oxides, and at least one element from group VIII, wherein the dioctahedral phyllosilicate 2:1 further comprises fluorine.
