A metathesis process for the conversion of olefines, in which an olefine is brought into contact with a solid catalyst system comprising, on a solid silica carrier, 0.1 - 40% by weight of a wolfram compound, under reaction conditions in which the catalyst system converts the olefine into olefines having a different molecular weight; the silica carrier being a magnesium oxide or titanium oxide-containing co-gel prepared by means of a co-gelling system. |
