    摘要: 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.

    摘要: Boron trifluoride is removed from coordination compounds contaminating organic liquids by contacting the contaminated liquid with silica. For example, boron trifluoride is removed from a boron trifluoride-n-butanol coordination compound contaminating a 1-olefin oligomer product by passing the contaminated liquid oligomer through a bed of silica.

    摘要: 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.

    摘要: 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.

    摘要: Spent boron trifluoride catalyst is removed from organic liquids by contacting the liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol. The boron trifluoride is recovered from the polyvinyl alcohol and is recycled for use as a catalyst.
