Patent Images
1. AN IMPROVED PROCESS FOR CHLORINATING ZIRCON ORE TO OBTAIN HIGH YIELDS OF BOTH ZIRCONIUM TETRACHLORIDE AND SILICON TETRACHLORIDE, WHICH COMPRISES INTRODUCING GRANULAR ZIRCON ORE OF ABOUT -65 TO +200 MESH AND CARBON IN A WEIGHT RATIO OF ABOUT 1:
- 1 ZIRCON TO CARBON INTO A FLUIDIZED BED REACTION ZONE, CONTINUOUSLYU PASSING A CHLORINE CONTAINING GAS THROUGH SAID ZONE TO MAINTAIN SAID BED IN FLUIDIZED EBULLIENT MOTION, MAINTAINING THE REACTION TEMPERATURE OF THE MASS WITHIN SAID FLUIDIZED BED WITHIN THE RANGE OF 1025 TO 1150*C., MAINTAINING THE WEIGHT RATIO OF UNREACTED CARBON TO TOTAL WEIGHT OF SOLIDS IN THE BED AT ABOUT 1;
2, REMOVING THE GASEOUS REACTION PRODUCTS FROM THE REACTION BED, AND SEPARATING AND RECOVERING THE ZIRCONIUM TETRACHLORIDE AND SILICON TETRACHLORIDE CONTAINED THEREIN.
