Abstract: The present invention relates to a catalyst comprising: (a) an aluminium-doped sulphated zirconium oxide, —with an aluminium content of 0.8 to 3.0% by weight of the catalyst, —with a cristallographic phase containing at least 80%, in particular at least 85% or at least 90%, of zirconium oxide in the tetragonal phase, —with a crystallinity index for the zirconium oxide of at least 55%, in particular of at least 60% or at least 65% or 70%; (b) a refractory oxide selected from silica and/or alumina; (c) a group VIIIB metal.
