    摘要： The present invention relates to a method for producing highly pure, granular silicon with a narrow particle-size distribution by decomposing silanes or halosilanes in a fluidised bed and epitaxially growing silicon on silicon seed particles, which method is characterised in that the gas containing silicon is supplied to the reaction chamber in an upward flow and the contents of the fluidised bed are separated in a continuous or discontinuous manner, whereby a particle stream from the fluidised bed is supplied to a separator mounted outside the fluidised bed, particles of the desired size are separated and undersized particles are returned to the fluidised bed. The invention also relates to a device and the use thereof for carrying out said method.

    摘要： A device for electrically heating a vertically erect chamber comprising several heating zones arranged vertically one above the other. The components of the device, with the exception of the insulating components, are made from graphite materials. Each zone (Z) comprises a number of supports (1), arranged in an essentially even distribution around the chamber for heating, which simultaneously serve as electrical supplies for the heater, and the heater for each zone (Z) is fixed at one end and longitudinally displaceable at the other end.

    摘要： A chemical reactor 1 for the reaction of fluid reaction mixtures is disclosed. The reactor includes at least one adiabatic reaction zone 2 with a catalyst bed 3 and at least one heat exchanger 4 downstream of the reaction zone 2. The heat exchanger 4 includes plates 5, 6 which are layered on top of one another and joined to one another. The individual plates 5, 6 have at least two separate fluid flow channels 7, 8 arranged in a predetermined pattern. The plates have fluid flow channels 7, 8 which are arranged so that the reaction mixture flows through the heat exchanger 4 in a first flow path direction and the heat-transfer medium used in the heat exchanger 4 flows through the heat exchanger 4 in a second flow path direction. The plates 5, 6 in the heat exchanger 4 are joined to one another by hard soldering.
