Abstract
Procedure for obtaining catalysts for the reform of hydrocarbons, mainly in order to obtain aromatic hydrocarbons, consisting essentially of a support, platinum, iridium and one or more elements that moderate the activity of iridium, and where the moderating elements are in a state metal; they are chosen from the group consisting of gallium, germanium, tin and arsenic; the total number of moderating element atoms is 0.5 to 4 per iridium atom; the proportion of gram-atoms of iridium and moderating elements, expressed in number of milliatoms-gram, is comprised between 0.5 and 10 per 100 g of the finished catalyst; and the proportion of platinum is comprised between 0.2 and 0.8% of the weight of the finished catalyst, more particularly between 0.25 and 0.65% of the weight of the finished catalyst; characterized in that it is provided, by impregnation, platinum, iridium and the moderating elements on porous supports.
