In a process for the dehydrocyclization of a dehydrocyclizable hydrocarbon contained in a dehydrocyclization feed stream which comprises contacting said dehydrocyclizable hydrocarbon in a dehydrocyclization zone under dehydrocyclization conditions in the presence of a dehydrocyclization catalyst, the improvement comprises carrying out said dehydrocyclization process in the presence of a metal chloride additive in said dehydrocyclization feed stream, said metal chloride additive being present in an amount sufficient to inhibit deactivation of such dehydrocyclization catalyst.

Hydrocarbon dehydrocyclization process

A fluid distributor means for distributing a liquid-containing fluid on the surface of a confined body of material, such as, a body catalyst or clay, including, a vertical tubular fluid inlet terminating in a plurality of radially-disposed tubes, mounted above the body of material; an annular tray between the radially-disposed tubes and the body of material and surrounding the radially-disposed tubes, having upstanding inner and outer edges to prevent fluid flow from the edges and having apertures for the passage of fluid therethrough and a plurality of baffles, equal in number to the number of radially-disposed tubes, mounted on the tray in positions to intercept fluid discharged by the tubes. A layer of inert particulate material may be disposed on the body of material below the tray.
