Claim 1
Independent Claim
142 words
IN THE PRODUCTION OF METAL OXIDE BY REACTION OF OXYGEN WITH A CHLORIDE OF A METAL OF THE GROUP CONSISTING OF TITANIUM SILICON AND ALUMINUM WHICH IS IN VAPOUR STATE AT 350*C., THE IMPROVEMENT WHICH COMPRISES ESTABLISHING A BED OF INERT PARTICLE OF A PARTICLE SIZE RANGE OF 40U1000U, INTRODUCING OXYGEN AND SAID METAL CHLORIDE INTO SAID BED TO FLOW THROUGH AND UNIFORMLY FLUIDIZE SAID BED, HEATING THE BED TO CAUSE THE METAL CHLORIDE TO REACT WITH THE OXYGEN, CARRYING EVOLVED METAL OXIDE FROM THE BED WITH THE GASES LEAVING THE BED, AND CONTROLLING THE TEMPERATURE OF THE BED BY WITHDRAWING A PORTION OF SAID INERT PARTICLES FROM SAID BED AT BED TEMPERATURE, AND ADDING TO THE BED, AND SEPARATELY FROM THE INTRODUCTION OF OXYGEN AND SAID METAL CHLORIDE, A FURTHER PORTION OF INERT PARTICLES AT A TEMPERATURE BELOW THE BED TEMPERATURE.
