Abstract

THE PRESENT DISCLOSURE PROVIDES FOR A CATALYST COMPOSITION CONTAINING AN INERT CATALYST CARRIER FORMED BY CALCINING A MIXTURE OF ALUMINA AND SILICA AT A TEMPERATURE BELOW 850*C. ONTO WHICH CARRIER ARE DISPERSED COPPER AND NICKEL AS ACTIVE METAL COMPONENTS, THE WEIGHT OF THE COPPER EXCEEDING THE WEIGHT OF THE NICKEL, THE WEIGHT OF THE CARRIER EXCEEDING THE WEIGHT OF THE ACTIVE METAL COMPONENTS, AT LEAST 25% BY WEIGHT OF THE ACTIVE METAL COMPONENTS BEING IN THE METALLIC STATE, AND THE REMAINING PERCENTAGE BEING IN THE FORM OF THEIR OXIDES. THE PRESENT INVENTION ALSO PROVIDES FOR THE USE OF THE AFOREMENTIONED CATALYST FOR SELECTIVELY HYDROGENATING ACETYLENIC HYDROCARBONS.
