A PROCESS FOR PREPARING SUBSTANTIALLY STRAIGHT CHAINED LIQUID OLEFINS WHICH COMPRISES POLYMERIZING AN ALPHA-OLEFIN HAVING FROM 2 TO ABOUT 10 CARBON ATOMS AT A TEMPERATURE OF FROM ABOUT -10*C. TO ABOUT 200* C. USING AS A CATALYST THEREFOR AN AMMONIATED MIXED METAL OXIDE ON ACTIVATED CARBON COMPOSITION IN WHICH THE METAL OXIDE COMPONENTS ARE (1) FROM ABOUT 3% TO ABOUT 12% BY WEIGHT OF AN OXIDE OF ZINC, AND (2) FROM ABOUT 1% TO ABOUT 12% BY WEIGHT OF COBALT OXIDE, SAID CATALYST COMPOSITION HAVING BEEN PREPARED BY AMMONIATING AN ACTIVATED CARBON, DRYING THE AMMONIATED ACTIVATED CARBON, IMPREGNATING THE AMMONIATED ACTIVATED CARBON WITH (1) A HEAT DECOMPOSABLE SALT OF ZINC, THE AMOUNT OF WHICH IS EQUIVALENT TO FROM ABOUT 3% TO ABOUT 12% BY WEIGHT OF THE OXIDE OF ZINC, AND (2) A HEAT DECOMPOSABLE SALT OF COBLT THE AMOUNT OF WHICH IS EQUIVALENT TO ABOUT 1% TO ABOUT 12% BY WEIGHT OF COBALT OXIDE, AND HEATING THE IMPREGNATED ACTIVATED CARBON THUS OBTAINED TO FROM ABOUT 200*C. TO ABOUT 300*C. IN AN INERT ATMOSPHERE.
