The invention relates to a catalyst containing at least one halogen, at least one group VIII metal and a shaped support comprising gamma alumina and optionally eta alumina, the catalyst being characterized in that the smallest dimension average of said support is between 0.8 and 2 mm and in that its halogen content is between 4.5 and 15% by weight. The invention also relates to the preparation of said catalyst, with, in the case where the halogen is chlorine, a preferred chlorination in the presence of CCl 4 or CHCl 3 . The invention also relates to the use of said catalyst in isomerization of normal C 4 -C 6 paraffins. |
