DRY CHLORINATION PROCESS TO PRODUCE ANHYDROUS RARE EARTH CHLORIDES |
| 摘要 |
A process for producing at least one rare earth chloride from an ore containing the at least one rare earth comprises: contacting the ore containing the at least one rare earth with reactants comprising a carbonaceous reducing agent, chlorine, and a boron-containing Lewis acid in a chlorination reactor to produce a gaseous product and a non-volatile chloride mixture comprising the at least one rare earth chloride. |

1. A process for producing at least one anhydrous rare earth chloride from an ore containing the at least one rare earth, the process comprising:
contacting the ore containing the at least one rare earth with reactants comprising a carbonaceous reducing agent, chlorine, and a boron-containing Lewis acid acting as a defluorination agent in a chlorination reactor to produce a gaseous product and an anhydrous non-volatile chloride mixture comprising the at least one rare earth chloride, the boron-containing Lewis acid being selected from the group consisting of: B(OH)3, BCl3, B2O3, Na2B4O7, and mixtures thereof. |
