Abstract
A process for upgrading residual portions of crude oils comprising metal contaminants and Conradson Carbon contributing components by the combination of thermal visbreaking with fluid inert solids and catalytic upgrading of naphtha and higher boiling components of thermal visbreaking in separate systems of riser conversion and solids regeneration is discussed. Heat management of the regeneration systems is restricted in substantial measure by a novel external solids heat exchange apparatus arrangement utilized to partially cool hot regenerated solids utilized in the solids regeneration systems.
