ABSTRACT:
A process for the production of aromatic hydrocarbons from petroleum fractions containing paraffins which comprises passing said charge in the presence of hydrogen at 400.degree. C.-550.degree. C. over a catalyst containing from 0.1 to 1.5% by weight of at least one metal selected from the group consisting of platinum, rhenium, iridium, tin and germanium and containing sulfur in a sulfur/metals atomic ratio of from 0 to less than 1, supported on a crystalline, aluminum silicate zeolite containing alkaline cations, said zeolite having a pore dimension larger than 6.5 Angstroms, wherein the catalysts are in fixed beds in two reactors or sets of reactors arranged in parallel and operate at a pressure on the order of from 0.5 to 8 absolute bars wherein when a reactor set (DHC.sub.1 ) is producing aromatic hydrocarbons the other reactor set (DHC.sub.2 ) is swept by the hydrogen produced by the first reactor set (DHC.sub.1) at a temperature adequate for reactivating the catalyst, then inverting the roles of the two sets.
