Abstract: Butadiene is made from a butene rich feed by passing a superheated butene rich feed including superheated steam and oxygen at a temperature of at least about 343° C. (650° F.) over a catalyst bed having a depth of over about 69 cm (27 inches) of granules of ferritic oxidative dehydrogenation catalyst. Inlet conditions being controlled such that the oxidative dehydrogenation reactions initially occur in the lower most layers of catalyst. Process control includes monitoring the temperature throughout the bed and increasing the inlet temperature in response to a drop in the temperature in the active layer, when the active layer of oxidative dehydrogenation catalyst begins to become deactivated so that the reaction zone moves upwardly in the oxidative dehydrogenation bed.

Abstract: The present discloses a process and catalyst therefor to selectively remove acetylenes from gaseous streams in the vapor phase. The process is particularly suitable for high yield recovery of olefinic hydrocarbons from gaseous streams in refinery processes.

Abstract: Cofeeding butylenes with amylenes in a catalytic oxidative dehydrogenation reaction substantially improves the conversion of the amylenes. The approved amylene conversion is obtained by the oxidative dehydrogenation of mixtures of amylenes and from 10 to 95 mole % butylenes.

Abstract: MTBE can be dissociated with high selectivity to isobutene and methanol over acid action exchange resin catalysts using very high LHSV, e.g. of 7 to 35 at pressure drops of 0.5 to 50 psig through the fixed bed at reaction pressure of 0.5 to 4 atmospheres and bed temperatures in a fixed bed tubular-reactor in the range of 90.degree. C. to 160.degree. C. Good conversions are obtained and undissociated MTBE and by-products of the dissociation may be recycled to a liquid phase MTBE synthesis.

Abstract: Conversions of over 80 mole % of n-butenes to oligomers can be obtained with less than 15 mole % C.sub.12 or higher oligomers by passing a predominantly C.sub.4 stream containing at least 40 mole % n-butenes through an acidic cation exchange resin at LHSV 2 to 5 at temperatures in the range of 80.degree. C. to 130.degree. C., in liquid phase by cofeeding from 1 to 5 weight %, based on the C.sub.4 stream, of methyl tertiary butyl ether, secondary butyl methyl ether, toluene or mixtures thereof.
