Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
86 words
A METHOD OF PREPARING A CATALYST SUITABLE FOR HYDROCARBON CONVERSION REACTIONS COMPRISING THE STEP OF CONTACTING A HALOGENATABLE INORGANIC OXIDE WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS OF ALKALI METALS AND ALKALINE EARTH METALS SO THAT SAID COMPOUND SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS OF ALKALI METALS AND ALKALINE EARTH METALS IS RETAINED BY SAID OXIDE IN AMOUNT FROM AT LEAST 1% TO 10% BY WEIGHT OF SAID INORGANIC OXIDE, AND CONTACTING SAID OXIDE WITH A CHLORINE CONTAINING COMPOUND OF GENERAL FORMULA
Claim 2
Independent Claim
86 words
A METHOD OF PREPARING A CATALYST SUITABLE FOR HYDROCARBON CONVERSION REACTIONS COMPRISING THE STEP OF CONTACTING A HALOGENATABLE INORGANIC OXIDE WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS OF ALKALI METALS AND ALKALINE EARTH METALS SO THAT SAID COMPOUND SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS OF ALKALI METALS AND ALKALINE EARTH METALS IS RETAINED BY SAID OXIDE IN AMOUNT FROM AT LEAST 1% TO 10% BY WEIGHT OF SAID INORGANIC OXIDE, AND CONTACTING SAID OXIDE WITH A CHLORINE CONTAINING COMPOUND OF GENERAL FORMULA
Claim 3
Dependent Claim
38 words
A PROCESS FOR THE ISOMERISATION OF AN OLEFINIC HYDROCARBON WHICH IS CAPABLE OF UNDERGOING DOUBLE BOND MIGRATION WHICH COMPRISES CONTACTING SAID OLEFINIC HYDROCARBON WITH A CATALYST AS CLAIMED IN CLAIM 1 AT A TEMPERATURE IN THE RANGE 0*C.-300*C.
