ABSTRACT:
A pretreatment method is disclosed for a hydrocarbon conversion catalyst formulation which results in significantly improved yield performance. The pretreatment method involves contacting a catalyst comprising a refractory support containing a platinum component, a tin component and a surface-impregnated promoter metal in the absence of hydrocarbons with a gas containing hydrogen at a temperature, pressure, and period of time sufficient to result in improved yield performance when compared to a non-pretreated catalyst.
