Abstract: The present disclosure provides methods and systems for converting ethanol and cracking hydrocarbons into ethylene and at least cracked products. A method to convert ethanol and cracking hydrocarbons includes: introducing a hydrocarbon feed into a riser of a fluid catalytic cracking reactor such that hydrocarbons in the hydrocarbon feed reacts in the presence of one or more fluid catalytic cracking catalysts to produce at least cracked products; and introducing an ethanol feed into an upper one third of a stripper of the fluid catalytic cracking reactor such that the ethanol reacts in the presence of spent catalyst flowing downwardly from a separator section of the fluid catalytic cracking reactor to produce at least ethylene.
