摘要： A degaser is disclosed for an outlet conduit into which solids are transferred from a fluidized bed within a larger vessel and comprises a curvilinear wall extending upward from the upper end of the outlet conduit and beveled at an angle to the vertical to form an outlet with a rim having a high side and a low side. The degaser is positioned with its high side far below the solids inlet into the vessel and its low side near the bottom of the fluidized bed. The biased rim may take various shapes and the degaser wall may extend only partially around the upper conduit end. Fluidizing gas can be introduced into the bed either above or below the low side of the degaser. The degaser may also include a baffle arranged within the vessel in cooperative relation to the rim.

摘要： Heat balance in a residual oil conversion unit can be controlled as a function of Conradson carbon of the feed, water added to the feed, hydrogen in the coke produced, CO.sub.2 /CO ratio, etc. Preferably, riser outlet temperature can be controlled to less than about 538.degree. C. (1000.degree. F.) at CO.sub.2 /CO flue gas ratios of 3/1 or less. Especially preferred are operations in a two-stage regenerator with cracking catalyst comprising at least 5000 ppm of Ni+V and residual carbon on regenerated catalyst of at least 0.1 wt. %. The contact time in the second stage of the regenerator being less than about 1/2 of that employed in the first stage, and with oxygen-lean gas being employed in the first stage. The heat transferred by the catalyst to the residual oil feed is preferably limited to about 500 to 1200 btu per pound of oil feed.

摘要： A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent de-asphalting and other heavy hydrocarbon fractions. These carbo-metallic oils contain quantities of coke precursors and heavy metal catalyst poisons substantially in excess of what is normally considered acceptable for FCC processing (fluid catalytic cracking) and substantial amounts of sulfur, nitrogen and other troublesome components may also be present. Such carbo-metallic oils are converted to the desired products in a catalytic conversion process. Named "RCC" (Reduced Crude Conversion) after a particularly common or useful carbo-metallic feed, the present process is by no means restricted to reduced crude or to oils of petroleum origin, having utility in the processing of oils from coal, shale and other sources.

摘要： A process for economically converting carbo-metallic oils to lighter products while adding magnesium chloride to modify heat output. The carbo-metallic oils contain 650.degree. F. and material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalents of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900.degree. to about 1400.degree. 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 spent, coke-laden catalyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen. The bed density is in the range of about 25 to about 50 pounds per cubic foot and the bed or beds are sustained by fluidization gas containing combustion-supporting gas having a linear velocity in the range of about 0.2 to about 4 feet per second. MgCl.sub.2 is added to the catalyst and is converted to MgO, which reduces sulfur oxide emissions, and a chlorine component, which reduces the CO.sub.2 /CO ratio, thereby reducing the heat output of the regenerator. The catalyst particles are retained in the regeneration zone or zones in contact with the combustion-supporting gas for an average total residence time in said zone or zones of about 5 to about 30 minutes to reduce the level of carbon on the catalyst to about 0.25% by weight or less. The regenerated catalyst is recycled to the reactor and contacted with fresh carbon-metallic oil.
