A process for the purification of an olefinic feedstock, particularly a feedstock for a disproportionation process over a rhenium heptoxide supported on alumina catalyst, by contacting the feedstock with a catalyst consisting essentially of a supported alkali metal at a temperature in the range -50 DEG to +80 DEG C and a pressure in the range 0 to 2,000 psig. and a Liquid Hourly Space Velocity in the range 0.01 to 100.
