ABSTRACT:
A process is described for converting residual oil with fluid catalyst particles which comprises passing an upflowing suspension of fluid catalyst particles at an elevated temperature upwardy through a riser reaction zone/atomizing a residual oil feed to be converted to a particle size commensurate with the particle size of the catalyst particles in the upflowing suspension; discharging the atomized residual oil at a velocity in excess of 300 ft./sec. for contact with said upflowing catalyst particle suspension; maintaining the temperature of contact between said catalyst particles and said atomized residual oil feed suspension sufficiently elevated to obtain up to 50 percent thermal conversion of the atomized oil feed and catalytic conversion thereof by an order of magnitude greater than obtainable with a less atomized oil feed; and separating the suspension vaporous products of the previous step from catalyst particles in a time frame less than two seconds.
