Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
120 words
THE PROCESS OF INITIATING THE REDUCTION OF SOLID NICKEL CHLORIDE (NICL2) WITH HYDROGEN BY A DRY GAS-TO-SOLID REACTION TO FORM METALLIC NICKEL IN A TEMPERATURE RANGE IN WHICH HYDROGEN AND NICL2 WILL NOT COMMENCE TO REACT TOGETHER TO ANY SUBSTANTIAL EXTENT IN THE ABSENCE OF A REACTIONINTIATING CATALYST, COMPRISING THE STEPS OF CONTACTING DRY SOLID NICL2, WHICH IS SUBSTANTIALLY FREE OF METALLIC NICKEL, WITH A GAS CONTAINING HYDROGEN AS ITS ESSENTIAL ACTIVE REDUCING INGREDIENT, WHILE MAINTAINING SAID NICL2 IN THE TEMPERATURE RANGE OF ABOUT 475* F. TO ABOUT 650* F. AND CAUSING THE REACTION TO START BY PROVIDING IN CONTACT WITH THE NICL2 AT LEAST ABOUT 0.1% (BY WEIGHT BASED UPON THE NICL2) OF METALLIC NICKEL AS A REACTION-INITIATING CATALYST.
