Mc Farland, C G

This patent describes a vapor phase process for the preparation of hydrocarbon monoolefins and diolefins comprising oxidative dehydrogenation of a stream of C/sub 3/ to C/sub 9/ hydrocarbon compounds to produce a product stream comprising, exclusive of any water present, 3.5 to 80 mol percent hydrocarbon monoolefins and diolefins and about from 0.0001 to 2.5 mol percent carbonyl compounds and 5 to 93 mol percent non-condensable gases. The improvement described here comprises contacting the product stream in vapor phase at a temperature in the range of 250/sup 0/ to 900/sup 0/C and containing less than 5 mol percent free oxygen with a solid catalyst for reducing the acetylene compounds in the product stream, the catalyst consisting essentially of zinc ferrite and nickel oxide. The Fe is the major metal component by weight, an alkaline earth metal oxide, carbonate or hydroxide of Mg, Ca, Sr or Ba, and about 0.5 to 30 weight percent of an alkali metal oxide, carbonate or hydroxide, based on the other metallic elements of Li, Na, K or Rh.
