ABSTRACT:
A process is provided for starting a catalytic hydrocarbon conversion reaction or using a hydrocarbon conversion catalyst into which a sulfur agent has been incorporated. In an inert atmosphere, the sulfur-impregnated catalyst is treated with dilute hydrogen to prevent excessive temperatures during the exothermic transformation of oxides into sulfides of the active metals of the catalyst.
