ABSTRACT:
The present invention relates to a process for the disproportionation of n-olefins comprising contacting the olefin feed with a catalyst composition comprising molybdenum oxide or tungsten oxide supported on silica. The catalyst composition is produced by impregnating a silica support with an alcoholic solution of a halide of a metal selected from molybdenum and tungsten, removing the alcoholic solvent by evaporation, and heat treating the impregnated support at an elevated temperature such that (a) the metal halide is converted to the corresponding oxide and/or an oxy-salt and (b) the halogen content thereof is reduced to less than 0.1% by weight of the total composition. By using a catalyst produced by this method, it is possible to carry out the process so as to selectively produce linear higher olefins.
