Abstract
Olefins are converted into other olefins having different numbers of carbon atoms by contact with a catalyst produced by contacting an inorganic refractory oxide support containing rhenium oxide with a promoting amount of at least one aluminum alkyl and, optionally, at least one tin alkyl compound under conditions suitable for aluminum and tin alkyl compounds to promote the activity of the rhenium oxide for the disproportionation reaction.
Claims16
A process for disproportionating olefins which comprises contacting at least one feed olefin having at least 3 carbon atoms per molecule under reaction conditions with a catalytic amount of a catalyst composition produced by contacting an inorganic refractory oxide containing rhenium oxide and a promoting amount of at least one aluminum alkyl compound and subjecting same to conditions suitable for said aluminum alkyl to promote the activity of said rhenium oxide for the disproportionation reaction.
A process for disproportionating olefins which comprises contacting at least one feed olefin having at least 3 carbon atoms per molecule under reaction conditions with a catalytic amount of a catalyst composition produced by contacting an inorganic refractory oxide containing rhenium oxide with a promoting amount in the range of about 1 to about 100 weight percent based on total weight of rhenium oxide catalyst of at least one aluminum alkyl compound of the formula AlR.sub.3 wherein each R independently can range from 1 to about 6 carbon atoms and subjecting the composition thus-produced to elevated temperature conditions of at least about 200.degree. C. and of an oxygen-containing gas to promote the activity of said rhenium catalyst oxide for the disproportionation reaction.
