PREPARATION OF FCC CHARGE FROM RESIDUAL FRACTIONS ABSTRACT OF THE DISCLOSURE A process for upgrading a petroleum charge of a crude oil or a residual fraction thereof which contains high boiling components of substantial Conradson Carbon number which comprises emulsifying water in said charge as the internal phase of a water in oil emulsion, contacting the emulsion of water in said charge in a confined rising vertical column with a finely divided solid contact material consisting essentially of an inert solid material having a microactivity for catalytic cracking not substantially greater than 20 at low severity, including a temperature of at least about 900°F. for a period of time less than 2 seconds and less than that which induces substantial thermal cracking of said charge, at the end of said period of time separating from said inert solid a decarbonized hydrocarbon fraction of reduced Conradson Carbon number as compared with said charge and reducing temperature of said separated fraction to a level below that at which substantial thermal cracking takes place to terminate said period of time. . ...
