Abstract: The present invention provides a method of producing a synthesis gas from a regeneration of spent cracking catalyst. The method includes introducing a spent cracking catalyst into a first regeneration zone I a presence of a first oxygen and carbon dioxide atmosphere and at a first regeneration temperature. For example, a temperature that does not exceed about 1400 DEG F, ad more preferable a temperature that ranges from about 1150 DEG F to about 1400 DEG F, may be used as the first regeneration temperature. The method further includes introducing the spent cracking catalyst from the first regeneration zone into a second regeneration zone in a presence of a second oxygen and carbo dioxide atmosphere, and producing a synthesis gas from cracking deposits located on the spent cracking catalyst within the second regeneration zone at a second regeneration temperature substantially grater than said first regeneration temperature. In a preferred embodiment, the second regeneration temperature ranges from about 1500 DEG F to about 1800 DEG F, and in a related embodiment is about 1800 DEG F.
