Abstract | The catalytic cracking method comprises the following steps: introducing a heavy oil raw material into a heavy oil riser reactor of a catalytic cracking device, and introducing a heavy oil cracking catalyst with carbon deposit into a first regenerator for regeneration; the light hydrocarbon raw material enters a light hydrocarbon riser reactor of the catalytic cracking device, and the carbon-deposited light hydrocarbon cracking catalyst is subjected to steam stripping and then enters a second regenerator for regeneration; introducing primary regeneration main air into the first regenerator to perform oxygen-deficient regeneration on the heavy oil cracking catalyst to be regenerated, introducing carbon monoxide-containing primary regeneration flue gas generated in the first regenerator into the second regenerator, and performing oxygen-enriched regeneration on the light hydrocarbon cracking catalyst to be regenerated in the second regenerator; and performing on-line analysis on primary regenerated flue gas com |
