A process of hydroreforming in the presence of a catalyst containing at least one refractory inorganic carrier, platinum, possibly at least one metal from Group VIII (palladium, nickel, and ruthenium), a halogen or compound thereof, and at least one additional metal M selected from among germanium,

A process of hydroreforming in the presence of a catalyst containing at least one refractory inorganic carrier, platinum, possibly at least one metal from Group VIII (palladium, nickel, and ruthenium), a halogen or compound thereof, and at least one additional metal M selected from among germanium, tin, lead, gallium, indium, and thallium, process in which said metal M, in the form of at least one organic compound, is introduced in situ into the reactor where the hydrocarbon charge will then be treated or into a prereactor that is connected to said reactor.

In a process for hydroreforming, comprising subjecting a hydrocarbon charge to hydroreforming conditions in the presence of a catalyst containing at least one carrier, platinum, at least one additional metal M which is tin, and halogen, the improvement comprising using a catalyst

[ We claim:] [1.]1. In a process for hydroreforming, comprising subjecting a hydrocarbon charge to hydroreforming conditions in the presence of a catalyst containing at least one carrier, platinum, at least one additional metal M which is tin, and halogen, the improvement comprising using a catalyst which is obtained by introducing at least one organic compound of said at least one additional metal M, into a calcined and activated catalytic mass, referred to as a precatalyst, which mass includes at least one carrier and platinum, with said additional metal M being introduced in pure or dilute form, in situ, into a reaction zone where the hydroreforming of the charge is to be done in the presence of said catalyst.
