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 germanium component, and a halogen component with a porous carrier material, is improved by sulfiding the catalytic component, prior to any contact with hydrocarbon, so that about 0.05 to 0.5 wt. % of sulfur is incorporated therein, thereby diminishing undesired exothermic hydrocracking and demethylation during initial operation of the process.
