Fluidized catalytic cracking unit system with integrated reformer-electrolyzer-purifier

A fluidized catalytic cracking unit system comprising:

• a fluidized catalytic cracking unit assembly comprising a first catalyst regenerator, a second catalyst regenerator, and a cracking unit, the cracking unit configured to output spent catalyst to the first catalyst regenerator;
• and
• a reformer-electrolyzer-purifier assembly comprising a reformer-electrolyzer-purifier cell, the reformer-electrolyzer-purifier cell comprising an anode section and a cathode section;
• wherein the anode section of the reformer-electrolyzer-purifier assembly is configured to receive an anode input stream comprising hydrocarbon gases and water;
• wherein the cathode section of the reformer-electrolyzer-purifier assembly is configured to produce a cathode exhaust stream comprising oxygen and carbon dioxide;
• wherein the first catalyst regenerator is configured to:
• receive the cathode exhaust stream;
• partially regenerate the spent catalyst and form carbon dioxide by burning carbon on the spent catalyst using the oxygen in the cathode exhaust stream;
• generate a flue gas comprising the carbon dioxide from the cathode exhaust stream, carbon dioxide formed from regenerating the spent catalyst, and residual oxygen from the cathode exhaust stream;
• wherein the second catalyst regenerator is configured to receive the partially regenerated spent catalyst from the first catalyst regenerator and finish regenerating the partially regenerated spent catalyst by reacting the partially regenerated spent catalyst with air;
• and
• wherein the fluidized catalytic cracking unit system further comprises a carbon capture assembly configured to cool the flue gas to condense carbon dioxide in the flue gas.
