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 due to the use of an oxygenation catalyst comprising at least three metals in a perovskite-type crystal structure. This combusted gas can be directly vented to the atmosphere after energy has been extracted from it for a useful purpose.

Abstract: A tungsten-free hydrotreating catalyst is produced by contacting a refractory metal oxide support with an aqueous impregnating solution formed from an ammoniacal solution of nickel fluoride, preferably predissolved, and an Mo.sup.+VI oxide. The impregnating solution consists essentially of NH.sub.4.sup.+, Ni.sup.++, Mo.sup.+VI and F.sup.-, said Ni.sup.++ and F.sup.- being supplied from nickel fluoride and preferably contains nickel and fluoride ions in a ratio of substantially 1 to 2, and is used in an amount necessary for impregnating by the incipient wetness technique in a one-step impregnation. The impregnated catalyst support is then heated to a temperature sufficient to drive off ammonia and thereby deposit fluorine, nickel and molybdenum. The resulting catalyst is highly active for hydrotreating lube oil feedstocks.

Abstract: A nickel-molybdenum catalyst composite is formed by a process which consists essentially of contacting a refractory inorganic oxide support with an aqueous, alkaline impregnating solution consisting essentially of NH.sup.+.sub.4, Ni.sup.++, SO.sub.4 .sup.- and MO.sup.+VI, with substantially all of the Ni.sup.++ being supplied from nickel sulfate, and heating said impregnated support to dry and calcine the catalyst composite. The calcination is an oxidative calcination conducted in the presence of an oxygen-containing gas at a temperature in the range of 427.degree. and about 566.degree. C. such that sulfate remains on said support. The resulting catalyst is used to desulfurize naphthas, middle distillate oils and asphaltic oils.

Abstract: A lube oil feedstock is subjected to hydrotreating in the presence of hydrogen and a fluorine-promoted catalyst comprising nickel and molybdenum on a support wherein the nickel and fluorine are derived from an ammoniacal solution of nickel fluoride. The catalyst can be prepared by contacting the support with an alkaline impregnating solution consisting essentially of NH.sub.4.sup.+, Ni.sup.++, MO.sup.+VI and F.sup.-, said Ni.sup.++ and F.sup.- being supplied from nickel fluoride, in a single step employing the incipient wetness technique. The impregnated support is thereafter heated to drive off the alkaline component of the solution and thereby deposit the fluorine, nickel and molybdenum on the support.

Abstract: An aqueous, alkaline impregnating solution for the one-step impregnation of fluorine, nickel and molybdenum onto a catalyst support is provided by admixing nickel fluoride, preferably an ammoniacal solution of nickel fluoride and an ammoniacal solution of Mo.sup.+VI to form a compatible impregnating solution consisting essentially of NH.sub.4.sup.+, Ni.sup.++, Mo.sup.+VI and F.sup.-. Nickel and fluorine ions are present in a ratio of substantially 1 to 2. The use of nickel fluoride in a predissolved ammoniacal solution for admixture with the ammoniacal solution of the Mo.sup.+VI renders the resulting impregnating solution highly suitable for impregnation of fluorine, nickel and molybdenum onto a catalyst support by the incipient wetness technique in one-step. The catalyst produced using the present impregnating solution is highly active for hydrotreating lubricating oils.

Abstract: An integrated in situ combustion process for recovering subterranean liquid and solid carbonaceous deposits in which the resulting flue gas of low heating value is combusted at substoichiometric conditions over two different oxidation catalysts in two combustion zones in series and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit.
