摘要： A process for the preparation of coated peroxygen compounds, in particular sodium percarbonate, by fluidized bed coating. By using a fluidized bed reactor with a radial inflow base, the passage openings of which allow the fluidized bed gas to emerge in the region of the opening at an angle of less than 35°, measured with respect to the horizontal, in the form of directed part streams, and in which are arranged spray nozzles, the pulse of which points in the same direction as the pulse of the fluidizing gas, it is possible to obtain products with an increased active oxygen stability. A circular reactor, the inflow base of which has lamellae overlapping like turbine blades and nozzles aligned in the direction of rotation of the fluidized bed is preferred.

摘要： Sodium percarbonate is produced by means of fluidized bed granulation. The process includes spraying an aqueous sodium carbonate solution and a hydrogen peroxide solution onto nuclei in a fluidized bed and evaporating the water. In the process of the invention, it is not necessary to use a phosphorus-containing crystallization inhibitor in order to avoid cloggings and incrustations in and on the nozzle. This is accomplished by spraying the solutions through separate channels in a single ternary atomizer nozzle, to provide external mixing of the solutions with respect to the nozzle.

摘要： This invention relates to a process for the production of granulates by fluidized bed spray granulation and to a device for this purpose. Liquid starting materials may be converted into granulates by fluidized bed spray granulation. In order to ensure elevated material throughput, numerous nozzles, which are moreover susceptible to plugging and encrustation, must be installed.The disadvantages of known processes may be overcome according to the invention by arranging at least two spray nozzles at least partially directed towards each other in such a manner and the quantity of spray is adjusted in such a manner that their spray jets collide within the fluidized bed and substantially no liquid strike-through occurs onto a surface delimiting the fluidized bed or out of the fluidized bed. The spray jets of two spray nozzles directed towards each other collide frontally or enclose an angle of less than 180.degree.; the angle is preferably between 150.degree. and 180.degree..The device according to the invention comprises a flow channel (1) with laterally arranged spray nozzles (8), wherein in each case two exactly opposing or staggered spray nozzles are oriented in such a manner that the spray jets collide within the fluidized bed. Sodium percarbonate production is exemplfied.

摘要： In order to increase active oxygen stability, sodium percarbonate is coated with single or multiple layers of various substances. Sodium percarbonate particles consist of a core of sodium percarbonate fluidized bed spray granulate and sodium sulphate, which may be partially hydrated, as the sole constituent of a single coating layer. The particles exhibit both elevated active oxygen stability and very good ensilability. The coating layer is applied by spraying an aqueous Na.sub.2 SO.sub.4 solution onto the particles to be coated, which were themselves produced by fluidized bed spray granulation, in a fluidized bed and vaporizing water at a fluidized bed temperature of 35 to 100.degree. C.
