KATALYSATORSYSTEM UND VERFAHREN ZUR HERSTELLUNG VON EPOXIDEN

The present invention relates to a catalyst system which is a mixture of at least two catalytic species, the first catalytic species providing dehydrogenation activity and the second catalytic species providing epoxidation activity and comprising silver. The present invention also relates to a process for the production of epoxides, in particular a process for the production of an epoxide from a mixture comprising an alkane and an alkene, which process comprises contacting said mixture comprising said alkane and said alkene and a source of oxygen with such a catalyst system comprising a mixture of at least two catalytic species, the first catalytic species providing dehydrogenation activity and the second catalytic species providing epoxidation activity and comprising silver.
