ABSTRACT:
A contaminating metal on a cracking catalyst used for the cracking of hydrocarbons is passivated by contacting the catalyst with a hydrocarbon gas or mixture of gases comprising molecules of three carbon atoms or less at passivation reaction conditions prior to the cycling of the catalyst to the cracking zone, which gas or mixture of gases is first saturated with water at specific conditions.
