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.

摘要： A chemical filter for use within an internal combustion engine lubrication system. The chemical filter employs filtration media including particles having internal pores and interstitial pores formed between adjacent particles. The internal pores and the interstitial pores collectively define filtration media pores, and a strong base material is associated with at least some of the internal pores. The filtration media has a surface area greater than or equal to 25 m2/gm that is derived from filtration media pores that are large enough to receive a combustion acid-weak base complex contained within oil flowing through the chemical filter. This enables an ion-exchange process to occur that immobilizes the combustion acids and regenerates the weak base, so as to extend the time intervals between oil drains, among other benefits.

摘要： A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The resultant closed system allows the oil drain intervals to be significantly extended.

摘要： A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The dispersant is the ideal weak base to neutralize combustion acid at the piston ring zone, carry the resultant weak base-combustion acid complex to the strong base in the oil filter, undergo ion exchange with the strong base, immobilize the acid in the oil filter and recycle back to the piston ring zone for reuse as an acid neutralization agent. The reduction or elimination of detergent from the lubricant will reduce the fouling of the emission filter and of deposit formation on engine parts such as the piston. The oil filter may also contain an additive which is slowly released into the lubricant. For example, a ZnDDP anti-wear additive may be slowly released from the oil filter to the lubricant. Because the ZnDDP has low molecular weight alkyl groups it has limited solubility in the lubricant. The rate of release is limited by the equilibrium concentration of the additive in the lubricant. As a result, a relatively constant concentration of the additive may be maintained in the lubricant. The resultant closed system allows the oil drain intervals to be significantly extended.

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.
