Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A CATALYST FOR HYDROCARBON CONVERSION REACTIONS CONSISTING OF A MASS OF PARTICLES HAVING A SURFACE AREA OF LESS THAN ABOUT 1 SQUARE METER PER GRAM EACH OF WHICH CONSISTS ESSENTIALLY OF METAL FROM THE GROUP CONSISTING OF METALLIC MOLYBDENUM AND A METALLIC ALLOY CONTAINING FROM ABOUT 1% TO ABOUT 33% ALUMILNUM AND THE BALANCE MOLYBDENUM, THE SURFACE OF EACH PARTICLE HAVING BEEN ACTIVATED BY OXIDIZING THE SURFACE BY EXPOSURE TO AN OXYGEN CONTAINING GAS AT AN ELEVATED TEMPERATURE WITHOUT OXIDIZING THE ENTIRE PARTICLE AND A SUBSEQUENT EXPOSURE TO A HYDROGEN CONTAINING GAS AT A TEMPERATURE BETWEEN 350*C. AND 700*C.
Claim 2
Dependent Claim
99 words
A CATALYST FOR HYDROCARBON CONVERSION REACTIONS CONSISTING OF A MASS OF PARTICLES HAVING A SURFACE AREA OF LESS THAN ABOUT 1 SQUARE METER PER GRAM EACH OF WHICH CONSISTS ESSENTIALLY OF METAL FROM THE GROUP CONSISTING OF METALLIC MOLYBDENUM AND A METALLIC ALLOY CONTAINING FROM ABOUT 1% TO ABOUT 33% ALUMILNUM AND THE BALANCE MOLYBDENUM, THE SURFACE OF EACH PARTICLE HAVING BEEN ACTIVATED BY OXIDIZING THE SURFACE BY EXPOSURE TO AN OXYGEN CONTAINING GAS AT AN ELEVATED TEMPERATURE WITHOUT OXIDIZING THE ENTIRE PARTICLE AND A SUBSEQUENT EXPOSURE TO A HYDROGEN CONTAINING GAS AT A TEMPERATURE BETWEEN 350*C. AND 700*C.
Claim 3
Independent Claim
103 words
THE METHOD OF CONVERTING A HYDROCARBON LIQUID WHICH COMPRISES SUBJECTING SAID HYDROCARBON AT CONVERSION TEMPERATURE TO THE ACTION OF A HYDROCARBON CONVERSION CATALYST CONSISTING OF A MASS OF SOLID METALLIC PARTICLES HAVING A SURFACE AREA OF LESS THAN ABOUT 1 SQUARE METER PER GRAM CONSISTING ESSENTIALLY OF METAL FROM THE GROUP CONSISTING OF MOLYBDENUM AND AN ALLOY CONTAINING 1% TO 33% ALUMINUM AND THE BALANCE MOLYBDENUM, EACH PARTICLE HAVING AN UNOXIDIZED INTERIOR AND AN ACTIVATED SURFACE LAYER FORMED BY OXIDIZING ONLY THE SURFACE AND THEREAFTER AT LEAST PARTIALLY REDUCING THE SAME BY THE ACTION OF A HYDROGEN CONTAINING GAS AT AN ELEVATED TEMPERATURE.
Claim 4
Independent Claim
103 words
