Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
A PROCESS FOR PREPARING AN IMPROVED CATALYST CONSISTING ESSENTIALLY OF NICKEL OXIDE ON A POROUS SUPPORT WHICH COMPRISES CONTACTING A POROUS SUPPORT WITH AN AQUEOUS SOLUTION OF A NICKEL COMPOUND READILY CONVERTIBLE TO THE OXIDE BY HEATING IN A NON-REDUCING AMBIENT SO AS TO ADSORB ON SAID SUPPORT BETWEEN 0.1 AND 10 WEIGHT PRECENT OF NICKEL IN THE FORM OF SAID COMPOUND, MAINTAINING SAID SOLUTION AT A TEMPERATURE IN THE RANGE OF 70*C. TO THE BOILING POINT THEREOF DURING THE CONTACTING STEP, DRYING THE RESULTING IMPREGNATED SUPPORT, THEREAFTER CONVERTING THE ADSORBED NICKEL COMPOUND TO THE OXIDE, AND THEREAFTER REPEATING, AT LEAST ONCE, THE CONTACTING, DRYING, AND CONVERSION STEPS.

TO THE BOILING POINT THEREOF DURING THE CONTACTING STEP, DRYING THE RESULTING IMPREGNATED SUPPORT, THEREAFTER CONVERTING THE ADSORBED NICKEL COMPOUND TO THE OXIDE, AND THEREAFTER REPEATING, AT LEAST ONCE, THE CONTACTING, DRYING, AND CONVERSION STEPS.
Claim 3
Dependent Claim
105 words
A PROCESS FOR PREPARING A SUPPORTED NICKEL OXIDE POLYMERIZATION CATALYST COMPRISING IMPREGNATING A POROUS PARTICULATE SUPPORT WITH AN AQUEOUS SOLUTION OF A NICKEL COMPOUND READILY CONVERTIBLE TO THE OXIDE BY HEATING IN A FREE-OXYGEN-CONTAINING AMBIENT BY INITIALLY CONTACTING SAID SUPPORT WITH AN EXCESS OF THE HOT AQUEOUS SOLUTION AT A TEMPERATURE IN THE RANGE OF 70*C. TO THE BOILING POINT OF THE SOLUTION SO AS TO ADSORB SAID NICKEL COMPOUND ON SAID SUPPORT, CONTINUING THE CONTACTING AT A TEMPERATURE IN SAID RANGE FOR AT LEAST 10 MINUTES, DRAINING EXCESS SOLUTION FROM SAID SUPPORT, DRYING THE RESULTING COMPOSITE, AND CONVERTING THE NICKEL COMPOUND TO THE OXIDE.
