Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
79 words
IN A PROCESS FOR THE PREPARATION OF A NORMALLY SOLID HYDROCARBON MATERIAL, STEPS WHICH COMPRISE CONTACTING ETHYLENE WITH A CATALYTIC MIXTURE PREPARED BY ADMIXING A METAL BOROHYDRIDE WHICH IS CAPABLE OF REACTING WITH WATER AT THE POLYMERIZATION TEMPERATURE TO PRODUCE HYDROGEN AND WITH A CATALYST COMPRISING ESSENTIALLY NICKEL OXIDE SUPPORTED UPON AN ACTIVATED CARBON, EFFECTING SAID CONTACTING AT AN EFFECTIVE POLYMERIZATION TEMPERATURE BETWEEN ABOUT 25* C. AND ABOUT 250* C., AND RECOVERING A NORMALLY SOLID HYDROCARBON MATERIAL THUS PRODUCED.
