Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
57 words
A METHOD FOR PRODUCING AN ALUMINA-COMBINED HALOGEN COMPOSITE WHICH COMPRISES REACTING ALUMINUM WITH LIQUID WATER IN THE PRESENCE OF A SUFFICIENT QUANTITY OF A MERCURY HALIDE TO YIELD AN ALUMINA-COMBINED HALOGEN COMPOSITE SUBSTANTIALLY FREE FROM UNREACTED ALUMINUM AND CONTAINING FROM 0.1% TO ABOUT 8% BY WEIGHT OF COMBINED HALOGEN BASED ON THE DRY WEIGHT OF THE COMPOSITE.
Claim 2
Independent Claim
57 words
A METHOD FOR PRODUCING AN ALUMINA-COMBINED HALOGEN COMPOSITE WHICH COMPRISES REACTING ALUMINUM WITH LIQUID WATER IN THE PRESENCE OF A SUFFICIENT QUANTITY OF A MERCURY HALIDE TO YIELD AN ALUMINA-COMBINED HALOGEN COMPOSITE SUBSTANTIALLY FREE FROM UNREACTED ALUMINUM AND CONTAINING FROM 0.1% TO ABOUT 8% BY WEIGHT OF COMBINED HALOGEN BASED ON THE DRY WEIGHT OF THE COMPOSITE.
Claim 3
Independent Claim
104 words
A METHOD FOR PRODUCING A CATALYST WHICH COMPRISES REACTING ALUMINUM WITH LIQUID WATER IN THE PRESENCE OF A SUFFICIENT QUANTITY OF A MERCURY HALIDE TO YIELD AN ALUMINA-COMBINED HALOGEN COMPOSITE SUBSTANTIALLY FREE FROM UNREACTED ALUMINUM, CONTAINING FROM ABOUT 0.1% TO ABOUT 8% BY WEIGHT OF COMBINED HAOLGEN AND FROM ABOUT 40% TO ABOUT 95% BY WEIGHT OF BAYERITE ALUMINA, DRYING THE RESULTANT ALUMINA-COMBINED HALOGEN COMPOSITE AT A TEMPERATURE OF FROM ABOUT 200*F. TO ABOUT 600*F., AND INTRODUCING TO SAID DRIED COMPOSITE A CATALYTIC COMPONENT SELECTED FROM THE GROUP CONSISTING OF THE METALS AND COMPOUNDS OF GROUP VIII OF THE PERIODIC TABLE, AND MIXTURES THEREOF.
