1. A process for the vapor phase production of ethylene oxide from ethylene and oxygen, said process comprising contacting ethylene in the vapor phase with an oxygen-containing gas at ethylene oxide forming conditions at a temperature in the range of from about 180°

  • C. to about 330°

    C. in the presence of a catalyst, wherein said catalyst is prepared by a process comprising;

    a) forming a mixture comprising at least one alumina component, ceramic bond, and a liquid medium;

    b) shaping the mixture into carrier bodies;

    c) drying and firing the bodies at a temperature of from 1200°

    C. to about 1500°

    C. to form porous carrier bodies;

    d) impregnating the porous carrier bodies with a titania generator in a liquid medium;

    e) calcining the impregnated bodies at a temperature sufficient to remove volatiles and generate titania;

    f) drying the carrier; and

    g) depositing a catalytically effective amount of silver and a promoting amount of alkali metal on said carrier.
