    摘要: The present invention provides a process for recovering transition metal tetrahalides from a waste stream coming from a catalyst manufacturing process by (a) establishing a mixed stream comprising transition metal tetrahalide and transition metal alkoxyhalides; (b) forming a falling liquid film from the mixed stream of step (a) at a temperature of from 25 to 85 °C and an absolute pressure of from 0.05 to 0.6 bar; and (c) establishing from the film of step (b) a first vapour stream containing from 90 to 100 % of recoverable components and a second liquid stream containing about 10 to 80 % of titanium haloalkoxides.

    摘要: A method and apparatus for the extraction of hydrocarbon products, alumina and soda ash from oil shales including various amounts of such chemicals, all based on solvent extraction of most of the hydrocarbons at temperatures around 400 °C. Such enables the alumina and soda ash values to be leached out with aqueous sodium carbonate leaching at reduced temperatures of around 150 °C with a corresponding reduced pressure. The soda ash monohydrate values are precipitated from the leach liquor at around 100 °C with the alumina values precipitated using CO2. Alternatively recycled fine aluminum trihydrate at 65 °C is used to produce alumina. Aluminum hydroxide is converted to acid alumina by an acid recycle stream that dissolves the alumina so any silica contaminant can be filtered out. Basic aluminum sulfate is then precipitated at about 200 °C and 250 PSIG for subsequent calcination at around 900 °C. This produces alumina and sulphate oxide gasses are recycled via a sulphuric-acid plant.

    摘要: An improvement is obtained in the method for the preparation of pellets of a metal halide as a light-emitting source of metal halide lamps, of which an extremely low moisture content is essential, in order not to increase the moisture content of the metal halide during pulverization and compression molding of the metal halide. Thus, a metal halide dehumidified in advance to have a moisture content not exceeding 5 ppm is pulverized and compression-molded in an atmosphere of an inert gas of which the dew point is -60 °C or lower so that substantially no moisture absorption takes place during processing.
