Abstract
A hydrocarbon conversion-catalyst regeneration process and apparatus is described for converting residual oils and regeneration of catalyst in two separate low and higher temperature regeneration stages stacked one above the other on the same or different vertical axis to provide catalyst at a temperature above the residual feed pseudo-critical temperature. A CO rich flue gas is recovered from the low temperature regeneration stage and a CO.sub.2 rich flue gas is recovered from the higher temperature regeneration stage. The temperature of the catalyst mixed with the residual oil feed is sufficient to obtain substantially complete vaporization of the residual oil charge. A special arrangement of apparatus is provided in the lower portion of a riser conversion zone to obtain the intimate vaporization contact between residual oil feed and the high temperature catalyst charged to the riser.
