ABSTRACT:
The performance of a hydrocarbon conversion process using a trimetallic acidic catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, a nickel component, and a halogen component with a porous carrier material, is improved by sulfiding the catalytic component, prior to any contact with hydrocarbon and after substantially all of the metallic components have been reduced to the corresponding metallic states, so that about 0.01 to 1 wt. % sulfur is incorporated therein, thereby diminishing undesired exothermic demethylation and other hydrogenolysis reactions during the initial operation of the process and markedly increasing the over-all stability of the process.
