| 摘要 |
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. |
