The invention relates to a method for converting ethylene into propylene consisting in reacting said ethylene with a supported metal compound comprising an aluminium oxide based support to which a tungsten hydride is grafted. Said reaction is carried out at a temperature ranging from 20 to 600&#xb0; C., preferably between 50 and 350&#xb0; C., at an absolute pressure ranging from 0.01 to 8 MPa, preferably between 0.01 and 1 MPa. A catalyst is regeneratable by introducing hydrogen at a temperature of 50-300&#xb0; C.

Method for converting ethylene into propylene

The invention relates to a method for metathesis of one or several reagents comprising a linear or branched hydrocarbon chain containing a double olefinic bond Csp&#x2550;Cspconsisting in reacting said reagent or reagents with a supported metal compound comprising an aluminum oxide-based support to which a tungsten hydride is grafted. Typically, each said reagent or reagents comprises from 2 to 30 carbon atoms. The reagent can be embodied in the form of olefin. The inventive method can be used, for example for producing propylene from ethylene and butane.
