摘要：An improved fluid catalytic cracking process providing improved product yieldand selectivity employs a regenerated hydrocarbon conversion catalyst having improvedactivity and a low level of residual coke, desirably less than 0.05 wt. % on catalyst,obtained by burning coke from spent catalyst under balanced conditions supportingsubstantially complete combustion of carbon monoxide with provision for recovery ofevolved heat by transfer directly to the catalyst particles particularly within a dilute-phase zone in the regenerator vessel. Effluent gas from the regenerator may bedischarged directly to the atmosphere with no discernible effect upon ambient airquality.
