Abstract
Olefins are converted into other olefins having different numbers of carbon atoms by contact with a catalyst comprising silica containing tungsten oxide and a promoting amount of silver under conditions suitable for silver to promote the activity of tungsten oxide for the disproportionation reaction.
Claims8
A catalytic composition suitable for the disproportionation of olefins consisting silica of and tungsten oxide promoted with an effective promoting amount of silver oxide.
A catalytic composition suitable for the disproportionation of olefins consisting of calcined silica support and tungsten oxide promoted with about 0.01 to about 10 weight percent silver, calculated as the metal, based on the tungsten oxide-silica material combination.
A process for preparing a disproportionation catalyst consisting of admixing a catalytically effective amount of tungsten oxide and silica support with a promoting amount of at least one of silver, silver oxide, and silver compounds convertible to silver oxide, and subjecting same to conditions suitable for silver to promote the activity of tungsten oxide for the disproportionation of olefins.
