Abstract
The invention relates to a method of preparing a dehydrogenation catalyst comprising a group VIII metal, a group IVA metal and a refractory oxide support. The method comprises stages of preparing the dry impregnation aqueous solution containing said group VIII metal, ammonia, either in solution or in gas form, and a complexing agent. It then comprises stages of aging the aqueous solution, of dry impregnation of the support, of maturing the impregnated support, of drying the impregnated support and of calcining the dried support.
