Abstract
The invention relates to a catalyst comprising a support, at least one noble metal M, tin, phosphorus and at least one lanthanide group element, the content of phosphorus element being comprised between 0.4 and 1% by weight, and the content of lanthanide group element(s) being less than 1% by weight with respect to the weight of the catalyst. The invention also relates to the process for the preparation of the catalyst and the use thereof in reforming.
