ABSTRACT OF THE DISCLOSURE A process for economically converting carbo-metallic oils to lighter products includes providing a converter feed containing 650°F+ material, the 650°F+ material being characterized by a carbon residue on pyrolysis of at least about 1 and by containing at least about 4 parts per million of Nickel Equivalents of heavy metal(s). The converter feed is brought together with a cracking catalyst to form a stream comprising a suspension of the catalyst in the feed, and the resultant stream is caused to flow through a progressive flow type reactor having an elongated reaction chamber which is at least in part vertical or inclined for a pre- determined vapor riser residence time in the range of about 0.5 to about 10 seconds at a temperature of about 900 to about 1400°F and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight. The catalyst is ballistically separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products in the reaction chamber by projecting catalyst particles in a direction established by the elongated reaction chamber or an extension thereof, the products being caused to make an abrupt change of direction relative to the direction in which the catalyst particles are projected. Adsorbed hydrocarbons are stripped from the separated catalyst, which is then regenerated with oxygen-containing combustion-supporting gas under conditions of time, temperature and atmosphere sufficient to reduce the carbon on the catalyst to about 0.25% by weight or less, while forming gaseous combustion product gases comprising CO and/or CO2. The regenerated catalyst is recycled to the reactor for contact with fresh feed.
