Catalytic cracking regeneration method with zero emission of carbon dioxide

The invention discloses a catalytic cracking regeneration method with zero emission of carbon dioxide. The method comprises the following steps that air is compressed and separated, obtained oxygen is used for catalyst regeneration, then the catalyst in obtained regenerated flue gas is separated, and flue gas pressure energy and heat energy are recycled; the regenerated flue gas heats a desorption tower kettle material to become low-temperature flue gas; the low-temperature flue gas is desulfurized, water vapor is separated and removed to obtain dry flue gas, one part of the dry flue gas is sent to a flue gas circulating compressor and pressurized for circulation, and carbon dioxide in the other part of the dry flue gas is absorbed and enriched to obtain lean gas and rich liquid; the rich liquid enters a desorption tower to be desorbed, and an alcohol amine solution and carbon dioxide are recovered; one part of the alcohol amine solution exchanges heat with flue gas discharged from a waste heat boiler and the
