Abstract: A method for recovering dissolved boron trifluoride from a hydrocarbon liquid in a vacuum column at moderate temperatures by trickling the hydrocarbon over metallic or ceramic packing in the column. Dissolved boron trifluoride catalyst is recovered from the crude oligomer reaction product resulting from the oligomerization of 1-decene.

Abstract: An integrated in situ combustion process for producing subterranean carbonaceous deposits in which the resulting flue gas of low heating value is combusted over an oxidation catalyst at substoichiometric conditions and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. An oxidation catalyst is provided for reducing carbon monoxide in the combusted flue gas comprising platinum and palladium.

Abstract: A method of homopolymerizing a 1-olefin to a product including the trimer and tetramer by utilizing boron trifluoride under pressure in the presence of a suspended particulate adsorbent material. For example, 1-decene is homopolymerized at a temperature of about 25.degree. C. in the presence of a suspension of about two weight percent silica and boron trifluoride at a pressure of 125 psi.

Abstract: The combustible component of a gas stream of low heating value is combusted using less than a stoichiometric amount of oxygen with minor production of carbon monoxide in the presence of an oxygenation catalyst comprising platinum and a cocatalyst selected from Groups IIA and VIIB, Group VIII up through atomic No. 45, the lanthanides, chromium, zinc, silver, tin and antimony. This combusted gas can be directly vented to the atmosphere after energy has been extracted from it for a useful purpose.

Abstract: An integrated in situ combustion process for producing subterranean carbonaceous deposits in which the resulting flue gas of low heating value is combusted over an oxidation catalyst at substoichiometric conditions and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. An oxidation catalyst is provided for reducing carbon monoxide in the combusted flue gas comprising platinum and at least one metal cocatalyst selected from Groups IA, II, III, VIIB and VIII up through atomic No. 45, the lanthanides, chromium, silver, tin and antimony.
