Olefins are converted into other olefins having different numbers of carbon atoms by contact with a catalyst comprising an inorganic refractory material containing at least one of tungsten oxide and molybdenum oxide and a promoting amount of at least one treating agent selected from chlorinated silicon compounds, thionyl chloride, and sulfuryl chloride under conditions suitable for the treating agent to promote the activity of tungsten and molybdenum oxides for the disproportionation reaction.

A process for preparing a disproportionation catalyst comprising forming a catalytically effective amount of calcined composite comprising at least one metal oxide selected from molybdenum oxide and tungsten oxide and an inorganic refractory material, contacting the calcined composite with a promoting amount of at least one treating agent selected from chlorinated silicon compounds comprising monosilanes selected from the group consisting of monomethyl-Tri-chlorosilane, isobutyltrichorosilane, dimethyldichlorosilane, trimethyl monochlorosilane, n-decyldichlorosilane, trichloromethyltrichlorosilane, 4-methylphenyltrichlorsilane, monochloromethyltrichlorosilane, cyclohexyldichlorosilane, siloxanes, and polysilanes, thionyl chloride, and sulfuryl chloride, and subjecting same to conditions suitable for said treating agent to promote the activity of said molybdenum and tungsten oxides for the disproportionation of olefins.
