Hydrogenation catalyst

Claim 1

THE METHOD OF PREPARING A FREE-FLOWING NICKEL HYDROGENATION CATALYST IN STORABLE AND USABLE FORM WHICH COMPRISES REDUCING A FINELY DIVIDED NICKEL COMPOUND CATALYST WHICH IS ADVERSELY AFFECTED BY OXYGEN, IN AN ATMOSPHERE OF HYDROGEN; COOLING SAID REDUCED CATALYST IN AN ATMOSPHERE OF HYDROGEN; DIRECTLY INTRODUCING SAID CATALYST INTO A SOLUTION CONTAINING A SOLVENT SELECTED FROM THE GROUP CONSISTING OF CYCLOHEXANE, METHYLCYCLOHEXANE, DECALIN, BENZENE, TOLUENE, DIOXANE, ISOOCTANE, ISOPENTANE, NORMAL HEPTANE, AND TETRALIN, AND A SUFFICIENT AMOUNT SO AS TO COAT SAID CATALYST WITH FROM 5 TO 100 WEIGHT PERECENT THEREOF OF A RUBBERY POLYMER SELECTED FROM THE GROUP CONSISTING OF UNHYDROGENATED POLYMERS OF BUTADIENE, UNHYDROGENATED COPOLYMERS OF BUTADIENE-STYRENE, UNHYDROGENATED COPOLYMERS OF ISOPRENE-STYRENE, SAID UNHYDROGENATED POLYMERS AND COPOLYMERS HAVING A MOONEY VALUE ABOVE ABOUT 50 (ML-4) MEASURED AT 212* F., HYDROGENATED POLYMERS OF BUTADIENE, HYDROGENATED COPOLYMERS OF BUTADIENE-STYRENE AND HYDROGENATED COPOLYMERS OF ISOPRENE-STYRENE PREPARED BY HYDROGENATING THE CORRESPONDING UNHYDROGENATED COMPOUND HAVING A MOONEY VALUE ABOVE ABOUT 15 (ML-4) MEASURED AT 212*F.; AND DRYING THE RESULTING MIXTURE SO AS TO REMOVE SAID SOLVENT AND LEAVE THE FINELY DIVIDED CATALYST COATED WITH THE RUBBERY POLYMER.
