Abstract: There is disclosed a method of suppressing misting or spatting from an oil-containing functional fluid, such as a chain saw lubricant, by blending with the functional fluid a mist suppressing effective amount of a copolymer of a C.sub.3 or C.sub.4 alpha-monoolefin and at least one other alpha-monoolefin having from 5 to about 20 carbon atoms, said copolymer having a viscosity average molecular weight of from about 500,000 to about 10 million.

Abstract: NaOH can be used to remove hydroperoxides from a lubricating oil provided the oil contains a metal thiophosphate. This extends the useful life of the oil and the equipment being lubricated. In a preferred embodiment, the NaOH is immobilized within the lubrication system of an internal combustion engine.

Abstract: A phosphorous- and sulfur-containing additive and its use to impart anti-wear and/or antioxidant properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmittion fluids, is disclosed. The additive comprises a mixture of products formed by simultaneously reacting (1) a betahydroxy thioether, such as thiobisethanol, and (2) a phosphorous-containing reactant, such as tributyl phosphite. The reaction is carried out under reduced pressure conditions (e.g., -40 KPa to -100 KPa) to limit the amount of thioether species in said additive to less than about 45 mole %.

Abstract: A synthetic lubricating fluid comprising at least one ester or its derivative represented by the formula ##STR1## wherein: n is an integer of 0 to 5 and m is an integer of 0 to 5, with the proviso that the sum of n+m is 1 to 10 inclusive;R.sub.1 is independently selected from hydrogen and C.sub.1 to C.sub.8 alkyl groups, andR.sub.2 is independently selected from hydrogen and C.sub.1 to C.sub.3 alkyl groups.

Abstract: Fouling is at least minimized when heating in a distillation unit a stream comprising C.sub.4 or C.sub.5 diolefins by a method wherein said distillation unit is flushed with an inert gas, thereafter nitric oxide is introduced in an amount ranging from 0.15 to 500, preferably from 5 to 30 gm of nitric oxide per square meter of internal surface area of said heating unit, the heating unit is thereafter flushed with inert gas and the C.sub.4 or C.sub.5 diolefin stream is introduced into the heating unit. This method may be applied to a depropanizer or a debutanizer the desorber and re-distillation of the CAA process for butadiene recovery, the extractive distillation, stripping tower and re-distillation of the ACN process for isoprene recovery, or extractive distillation, stripping tower and re-distillation of the ACN process for isoprene recovery.

Abstract: Methanol and synthetic natural gas are produced concurrently by introducing a carbonaceous material into a gasification zone, and thereafter, passing sequentially the synthesis gas thus formed through a water gas shift conversion zone, a sulfur compound and carbon dioxide removal zone, a methanol synthesis zone and a methanation zone.

Abstract: Novel hydrogenation catalysts are formed by impregnating a suitable support material with an aqueous solution of a salt of a transition metal; heat-treating the impregnated support at a temperature above 500.degree.F. to form chemical complexes on the surface of the support and to drive off moisture and absorbed oxygen; activating the surface complex by contacting the impregnated support with a soluble organometallic compound wherein the metal constituent is selected from Groups I, II and III of the Periodic Chart of the Elements, and thereafter treating the activated support material in the presence of a gaseous stream containing hydrogen at a temperature of at least 300.degree.F. to form a highly stable heterogeneous catalyst. The novel supported catalysts of the instant invention have been found to be highly active for the hydrogenation of organic compounds under extremely mild conditions.

Abstract: Supported iridium-containing hydrocarbon conversion catalysts which are at least partially deactivated due to the deposition of carbonaceous residues thereon during contact with hydrocarbons are regenerated by (1) contacting the catalyst with oxygen to burn at least a portion of the carbonaceous residues from the catalyst, (2) contacting the carbonaceous residue-depleted catalyst with an elemental halogen-containing gas at a temperature of less than about 850.degree.F., (3) contacting the treated catalyst with hydrogen at elevated temperatures to reduce a substantial portion of the iridium present in the catalyst to its metallic form, and (4) contacting the catalyst from step (3) with an elemental halogen-containing gas at a temperature of at least about 850.degree.F. Steps (3) and (4) may be repeated, in sequence, at least one additional time to redisperse the iridium catalyst component to a highly active, high surface area state.
