Abstract
The invention relates to a method of preparing a reforming catalyst comprising a group VIII metal, a halogen, at least one metal selected from the group made up of the group VIIB metals and group IVA metals, a refractory oxide support. The method comprises stages of preparing a dry impregnation aqueous solution containing ammonia, either in solution or in gas form and a complexing agent, of aging the aqueous solution, of dry impregnation of the support, of maturing the impregnated support, of drying and of calcination.
