摘要： A carbo-chlorination process is disclosed for selectively producing AlCl3 from an alumina-containing feedstock, comprising introducing the following into a fluidized bed reactor maintained at 600-700° C.: (a) dried and calcined feed stream comprising the alumina-containing feedstock and a carbon feed; (b) chlorinating agent; (c) selectivity agent; (d) dried air; and optionally (e) off-spec AlCl3. The process further includes removing a vapor stream from the reactor in which preferably about 75-80%, of the alumina present in the reactor is converted to AlCl3; and also removing a solid raw pozzolan stream from the reactor, wherein about 90-99% of the silica present in the reactor remains unconverted and exits the reactor through the solid raw pozzolan stream. The vapor stream comprising AlCl3 is purified to create an AlCl3 product stream comprising preferably greater than about 99.99% AlCl3. The raw pozzolan product is classified to remove coke and create a final pozzolan product having a strength activity index (SAI) in the range of 80-160, per ASTM 618.

摘要： Fluidizable particulate solids are removed from a first zone operating at a relatively higher temperature and pressure to a second zone or collector operating or maintained at a lower temperature and pressure by an improved drain or particle removal system. The improved system includes moving the particles from the first zone downwardly within a substantially vertical inlet conduit or leg into the lower regions of a first chamber and upwardly through that chamber under fluidized particle transport conditions energized by a fluidizing media provided in the chamber. The particles move to a second chamber by overflowing a weir separating the first and second chambers and are mixed with cooler particles which extract heat within the second chamber under fluidized particle transport conditions energized by a second fluidizing gas source which further transports the particles to the collector or second zone. Heat is removed from the second chamber by indirect heat exchange. The volume of fluidizing gas for the second chamber is much larger than that for the first chamber and provides for particle flow rate control in combination with a flow restriction. Particle flow is interrupted by stopping the particle flow out of, and the gas flow into, the second chamber while maintaining fluidizing gas flow into the first chamber and the inlet leg. The system is particularly suited to draining unreacted alumina from a chlorination reactor for producing gaseous aluminum chloride from particulate alumina.

摘要： The efficiency of a given reactor for the conversion of aluminum oxide bearing starting material by means of reducing and chlorinating gases or of carbon coated aluminum oxide bearing starting material by means of chlorinating gases in a solid/gas fluidized bed to yield aluminum chloride is improved by the addition of an inert, solid dilution agent to the bed. Whereas, as a result of the chemical reaction, the average particle size and bulk density of the reagent decreases in a batch process, and in a continuous process an equilibrium value is reached, the average particle size and the bulk density of the inert material remains unchanged. An initial average particle size of 60-80 microns proved successful; quartz, corundum, magnesium oxide of similar particle size and bulk density was added as dilution agent, and a gas flow rate of 2 to 30 cm/sec was attained along with quantitative conversion of the gaseous reagent. The increase in the space-time-yield of a fluidized bed reactor, measured by the conversion achieved before onset of breakthrough in the fluidized bed, amounted to 58 to 65%.
