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.

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. The cracking catalyst comprises crystalline aluminosilicate contained in a substantially alumina-free inorganic oxide matrix.

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 conditions include a temperature in excess of 1300. degree.
