摘要： The method for the metathesis of original linear or branched alkanes consists in reacting this or these original alkane(s) on a catalyst comprising a support formed by a solid oxide on which are grafted and dispersed metal atoms in hydride form, these metal atoms having high degrees of unsaturation. It concerns in particular the hydride of metals of groups 5 and 6 of the periodic system of elements and more particularly tantalum, tungsten and chromium.

摘要： The present invention relates to a catalyst system which is a mixture of at least two catalytic species, the first catalytic species being a dehydrogenation catalyst and the second catalytic species being an epoxidation catalyst 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 an alkane or a mixture comprising an alkane and an alkene, which process comprises contacting said alkane or 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.
