ABSTRACT:
Sulfur oxides in flue gas formed during cracking catalyst regeneration are reacted with a zeolitic crystalline aluminosilicate containing sodium cations in the catalyst regenerator to form a sulfur-containing solid, and the sulfur component is removed from the crystalline aluminosilicate in the cracking reactor by contacting the sulfur-containing solid with the hydrocarbon feed.
