摘要： Piston deposits resulting from neutralizing combustion acids present in the lubricating oil circulating within the lubrication system of an internal combustion engine are reduced or eliminated by first contacting the acids with a soluble weak base in the piston ring zone of the engine to form soluble neutral salts containing the weak base and the combustion acids. Thereafter, the neutral salts are contacted with a heterogeneous strong base immobilized within the lubrication system but outside of the piston ring zone. The strong base displaces the weak base from the neutral salts, returning the weak base to the oil for recirculation to the piston ring zone for further use. The remaining strong base/combustion acid salts are immobilized as deposits with the strong base rather than on the piston. In a preferred embodiment, trioctadecyl amine is the weak base and zinc oxide is the strong base. In a particularly preferred embodiment, the strong base is incorporated on a substrate, preferably a cement binder.

摘要： A method, composition and filter for reducing the presence of sludge or varnish precursors in a lubricating oil circulating within an internal combustion engine. The lubricating oil containing sludge or varnish precursors is contacted with discrete particles of an oil insoluble, oil wettable compound having an antioxidant functional group and/or a dispersant functional group, which are capable of complexing with sludge or varnish precursors. Preferably the compounds comprises a crosslinked amine having ethylene amine functionality. The starting polyethylene amines have a number average molecular weight in the range of about 100 to about 60,000, preferably 200 to 250 and are crosslinked with a silicon oxide, silane, silicate, epoxide, quinone, or phenol-formaldehyde crosslinking agent. The particles are encaged within a one or two stage oil filter together with filtering media such as chemically active filter media, physically active filter media and inactive filter media.

摘要： Used lubricating oils can be rejuvenated by passing the oil through a filter system comprising a hollow solid composite that contains a thermoplastic binder and an active filter media of a chemically active filter media, a physically active filter media, or mixtures thereof. In a preferred embodiment, the composite is formed by forcing a substantially uniform mixture of thermoplastic binder particles, active filter media particles, solvent 600 Neutral base oil, and sodium stearate through an extrusion die of substantially uniform cross-section, wherein the mixture is subjected to heat, pressure, and cooling to consolidate the mixture so that it emerges from the die as a hollow solid composite. Most preferably, the composite will surround an inactive filter media located within the filter system.

摘要： Deposit formation on the interior surfaces of structures confining heated hydrocarbon fluids such as refinery units, particularly preheating stages associated with process units such as distillation units, hydrotreaters and thermal crackers, is inhibited by incorporating in the feed stock a small percentage (usually at least about 0.0005 weight percent) of a macrocyclic polyamine formed by cyclodehydration of reaction products of hydrocarbon substituted succinic anhydrides or carboxylic acids with poly 3-amino propyl compounds or by acylation of macrocyclic polyamine and polycyclic polyamines with hydrocarbon substituted succinic anhydride or carboxylic acids. It is desirable in some instances to dissolve additionally in the hydrocarbon fluid such as a feed stock along with the macrocyclic polyamine an oil-soluble dispersant, antioxidant and mixtures thereof.

摘要： Novel filter elements for sequestering acids from oil or fuel, the strong base floes that comprise the filter elements, and methods of their preparation and use are disclosed. The filter elements comprise a mechanically linked interlocking fiber matrix interspersed with strong base particle floes wherein the strong base particles constitute at least 30% by weight of the filter element. Certain filter elements may be useful for sequestering acids or neutralized acids in certain oils or fuels, for example, the acids originating in the combustion and lubrication system of an internal combustion engine or those contained in oils in an oil circulation system. Other filter elements may be useful for reducing oxidation of an oil.
