    摘要： A fluidized bed reactor system comprises a vessel (10) adapted to contain a fluidized bed, a plurality of fluid injector means (24) mounted through the vessel wall (20) for injecting and distributing a fluidizing medium into the lower portion of the vessel, each injector means being made up of an elongated injector having a nozzle end (26) projecting into the vessel. The injector is withdrawably mounted through the vessel wall and has at least one downwardly directed orifice (28). Shield means (32) are provided which are mounted on the vessel wall above the injector extending along the length of the injector for maintaining an opening in the bed when the injector is withdrawn. The opening is substantially equivalent to the length of the injector. The reactor system further includes fluid supply means (48) in fluid communication with each elongated injector (24) for supplying the fluidizing medium to each nozzle end (26). When it is required to replace the injector due, for example, to clogging of the orifices or deterioration, the injector is withdrawn from the vessel, replaced or repaired and then inserted into the vessel, The shield means allows for the easy insertion of the injector into the vessel by maintaining an opening in the bed, whether fluidized or non-fluidized. The fluidized bed reactor system allows for the replacement or repair of injectors without the necessity for shutting down and/or cleaning out the vessel.

    摘要： An improved process for the production of vanadium chlorides is provided wherein vanadium oxide is reacted with chlorine and reactant carbon to produce substantially pure vanadium chlorides and an effluent stream containing vanadium chlorides and unreacted chlorine and the effluent stream is contacted with adsorptive carbon to adsorb the vanadium chlorides and chlorine in the effluent and the adsorptive carbon containing the adsorbed vanadium chlorides and chlorine is recycled as reactant carbon.
    In the process vanadium oxide and chlorine are fed to a reactor (22) containing reactant carbon in fluidized form. The reaction mixture is fed via a cyclone (34) first to a condensers (36) and (40). The gaseous material from condenser (40) forms a part of an effluent stream (66). The effluent stream (66) is passed through an adsorber (68) containing adsorptive carbon. The adsorptive carbon having adsorbed therein vanadium chlorides and chlorine is passed to a storage area (78) where it is mixed with make up reactant carbon and recycled as reactant carbon.

    摘要： The present invention relates to a method for manufacturing a crystalline oxidic compound comprising an alkaline metal and a valve metal, to a crystalline oxidic compound as obtained by the method, and to its use as a ferroelectric material; as a coating material for electrode materials in batteries, specifically in solid-state batteries; or in digital printing, especially on a polymeric substrate.
    Herein, the method for manufacturing a crystalline oxidic compound comprising an alkaline metal and a valve metal comprises the following steps:
    a) mixing an alcoholate of an alkaline metal and an alcoholate of a valve metal in a composition of an oxygenated organic solvent and hydrogen peroxide at room temperature;
    b) adding an acid selected from at least one of nitric acid or hydrochloric acid at room temperature, whereby a solution is obtained;
    c) drying the solution at an elevated temperature of 50 °C to 150 °C, whereby a powder comprising the at least one crystalline oxidic compound comprising the alkaline metal and the valve metal is obtained.
    This manufacturing method operates at a low ambient working temperature, especially below 200 °C, and, thus, allows a direct manufacturing of crystalline oxidic compounds without interaction with a substrate and/or on a substrate which is not capable of tolerating higher temperatures during the manufacturing of crystalline oxidic compounds without deformation and/or deterioration. A further advantage of the low ambient working temperature is that a diffusion of elements from the at least one crystalline oxidic compound as coating material into the substrate can be avoided.
