    Abstract: The present invention relates to the production of metal oxide from metal salts, in particular from aluminum hydroxide, wherein the metal salt is preheated in a first preheating stage, precalcined in a second preheating stage and calcined to metal oxide in a fluidized-bed reactor, and wherein the product obtained then is cooled in at least one suspension heat exchanger and subsequently in a multi- stage indirect cooler. To reduce the energy demand of a calcining plant, fluidizing air is supplied to the reactor with a temperature of up to 150 °C, and before entering the first preheating stage the metal salt is at least partly supplied to a hydrate drier in which it is indirectly heated with heat transfer medium from the first stage of the indirect cooler and dried.

    Abstract: In accordance with the invention, refining raw materials containing organic constituents, such as raw materials containing oil and/or bitumen, in particular oil or tar sand or oil shale, is effected with the following steps: supplying the raw materials to an expulsion stage and expelling a hydrocarbonaceous, in particular oil-containing vapor at a temperature of e.g. about 300 to 1000°C, supplying the hydrocarbonaceous vapor expelled in the expulsion stage and/or in a gasification stage downstream of the expulsion stage to a processing stage, in which the same is further processed e.g. by cracking, coking and/or hydrotreating, separating the products obtained in the processing stage and withdrawing the same, introducing the solids left in the expulsion stage and/or in the gasification stage including the non-evaporated fractions of heavy hydrocarbons into a combustion stage, burning the heavy hydrocarbons left in the solids in the combustion stage at a temperature of e.g. about 600 to 1500°C, preferably e.g. about 1050 to 1200°C, recirculating hot solids from the combustion stage into the expulsion stage and/or the gasification stage, wherein the oxidizing atmosphere of the combustion stage is separated from the atmosphere of the expulsion stage and/or the gasification stage by means of a blocking device, and supplying water into the expulsion stage and/or the gasification stage.

    Abstract: A process for producing metal oxide from a metal salt includes supplying a first part of the metal salt to a hydrate drier so as to indirectly heat the first part of the metal salt in the hydrate drier using a heat transfer medium from a first stage of a multi-stage indirect cooler so as to dry the first part of the metal salt in the hydrate drier and so as to control a waste gas temperature of the process. A second part of the metal salt is guided as a partial stream past the hydrate drier. The metal salt is preheated in a first preheating stage and precalcined in a second preheating stage. The metal salt and a fluidizing gas having a temperature of 150° C. or less are supplied to a fluidized bed reactor so as to calcine the metal salt to form a metal oxide product. The metal oxide product is cooled in at least one suspension heat exchanger and then in the multi-stage indirect cooler.

    Abstract: When producing metal oxide from metal salts, the metal salt, in particular aluminum hydroxide, is dried and preheated in a first preheater (2) at a temperature of 100 to 200°C, precalcined in a second preheater (5) at a temperature of 300 to 400°C and then calcined in a reactor (8) at a temperature of 850 to 1100°C to obtain metal oxide, in particular alumina. After precalcination in the second preheater (5), a partial stream of the metal salt is branched off and supplied to a mixing tank (14), in which it is mixed with the metal oxide withdrawn from the reactor (8).
