METHOD FOR REDUCING THE FORMATION OF FLUOROCARBONS IN MOLTEN SALT ELECTROLYSIS |
| 摘要 |
A sensor is provided for measuring the concentration of a fluorocarbon in the offgas during molten salt electrolysis of metal compounds. The measurement takes place at time intervals of less than 10 seconds and a controller initiates reduction in an electrolysis voltage if a fluorocarbon limit value of 25 ppm is exceeded. |

1. A method for reducing formation of fluorocarbons in molten salt electrolysis of metal compounds, comprising:
measuring, by a sensor, concentration of a fluorocarbon in offgas at time intervals of less than 10 seconds; and initiating, by a controller, a reduction in at least one of an electrolysis voltage and an electrolysis current density at an anode, when a fluorocarbon limit value of not more than 100 ppm is exceeded. |
