摘要: Method of regenerating an Re2O7-doped supported catalyst which has been deactivated by use in the metathesis of a hydrocarbon mixture comprising C2-C6-olefins (C2-6= feed) (deactivated catalyst), which comprises treating the deactivated catalyst with an inert gas (regeneration gas K1) at from 400 to 800° C. and subsequently treating the deactivated catalyst which has been pretreated with regeneration gas K1 with an oxygen-containing gas (regeneration gas K2).
