Abstract: A process for producing carbon molecular sieves for the separation of oxygen and nitrogen, whereby finely ground hard coal particles are oxidized with air in a fluidized bed, the coal is then formed after the addition of water and binders and carbonized at temperatures of 800.degree.-900.degree. C., subsequently activated with steam at temperatures of 800.degree.-900.degree. C. and the preliminary product of the low-level activation is treated with carbon splitting hydrocarbons. Starches obtained by reacting agglutinized starches with sulphamates are used as binders.

Abstract: A carbonaceous adsorbent impreganted with elementary sulfur is produced by mixing the adsorbent with elementary sulfur in a quantity required for the desired impregnation, heating the mixture to a temperature between 120.degree. and 300.degree. C., maintaining this temperature over a time period of between 1 and 40 hours, and then cooling the mixture.

Abstract: A method for thermal treatment, especially drying, of finely particulated bulk material comprises the steps of stirring the material in a reactor by means of a rotating stirrer while simultaneously discharging a heated gas under pressure through openings in a hollow arm of the stirrer so as to form in the reactor a whirling fluidized bed from the material, and introducing the necessary amount of heat for the thermal treatment of the material at least in part through a heat exchanger extending into the whirling fluidized bed.

Abstract: A reactor for the continuous thermal treatment of solids, particularly carbonaceous adsorbents comprises two superimposed fluidizing beds, below them a combustion chamber for receiving a fuel- or oil-air mixture, an intermediate regeneration space between the fluidizing beds and a similar space above the upper fluidizing bed. A gas outlet is provided in the top regeneration space to which also the inlet for the material to be treated leads. The outlet for the treated materials is provided on the intermediate regeneration space. The two spaces are connected by a channel through which the overrun of treated material passes from the upper to the intermediate regeneration space. This channel leads from the upper space through the wall of the reactor to the outside and reverts then through the wall back into the intermediate space. Valve means are provided for regulating the flow in the connecting channel.

Abstract: Bodies are press-molded from a mixture of particulate fuel and a binder. These bodies are heated to a temperature between about 600.degree.-900.degree. C. in a rotary furnace to degas them. The degassing is carried out without subjecting the bodies to mechanical stresses and without permitting combustion of the expelled volatile gases. The resulting shaped coke has a greatly improved abrasion resistance.

Abstract: The reactor has a reactor chamber bounded by a peripheral wall, and the reactor chamber is subdivided by an upright partition wall into an inlet chamber and an outlet chamber. The partition wall extends transversely of the chamber and has free ends each of which is spaced from a juxtaposed portion of the peripheral wall by a distance equal to between substantially 10-30% of the cross-sectional dimension of the reactor chamber in a plane connecting these juxtaposed wall portions. The partition wall is laterally offset by between substantially 10 - 30% of the diameter of the chamber in the direction of offset so that the inlet chamber is larger than the outlet chamber.
