    • The invention pertains to a method for supplying hydrogen fluoride as feed material to an electrolytic cell (electrolyzer) for (electrolytically) generating elemental fluorine from a molten salt electrolyte, which comprises transferring hydrogen fluoride (HF) from (a) a hydrogen fluoride supply unit via (b) a hydrogen fluoride supply line to (c) to the electrolytic cell, wherein the required amount of hydrogen fluoride feed for a defined fluorine production capacity is fed into the electrolytic cell, preferably as gaseous HF, with a substantially lower HF feeding quantity per hour (kg/h) over a prolonged feeding interval compared to a full (maximum) HF feeding capacity of 80 kg/h of the supply line and the related short full HF feeding interval, as in hitherto conventional methods. In another aspect the invention also concerns an electrolytic cell for the generation of elemental fluorine by the electrolysis of a molten HF adduct of KF, in which the HF supply line is adapted to the method for supplying hydrogen fluoride as feed material according to the invention.
    • 本发明涉及一种将氟化氢作为原料供给电解槽(电解槽),用于(熔解)从熔盐电解液产生元素氟的方法,该方法包括从氟化氢供应单元(a)中转移氟化氢(HF) 通过(b)到(c)的氟化氢供应管线到电解池,其中所需量的氟化氢进料定义的氟生产能力被进料到电解池中,优选作为气态HF进料,其中HF供给 与迄今为止常规方法一样,供给线的80kg / h的全(最高)HF供给能力和相关的短全HF供给间隔相比,在长时间的供料间隔内每小时的量(kg / h)。 在另一方面,本发明还涉及通过电解KF的熔融HF加合物来生成元素氟的电解池,其中HF供应管线适用于根据本发明的供料氟化氢的方法。
