摘要： An overbased calcium sulfonate grease composition comprising a reduced amount of overbased calcium sulfonate, calcium hydroxyapatite, base oil, one or more converting agents, and one or more complexing acids if a complex grease is desired. The calcium sulfonate grease composition improves thickener yield and expected high temperature utility as demonstrated by dropping point. A method of making the composition comprising the steps of mixing the calcium sulfonate and base oil, adding the calcium carbonate either before or after conversion, adding one or more converting agents, and adding one or more complexing acids. All or a portion of one or more of the complexing acids may be added with or prior to the one or more converting agents.

摘要： Methods are provided for producing Group III base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group III base stocks can have a viscosity at 100° C. and/or a viscosity at 40° C. that is greater than the corresponding viscosity for a conventional Group III base stock. Additionally, the resulting Group III base stocks can have one or more properties that are indicative of a high quality base stock.

摘要： Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point.

摘要： A comb polymer can be used for reducing a Noack evaporation loss of a lubricant composition, especially of an engine oil composition. Application of the comb polymer to the lubricant composition can bring about the desired reduction. The comb polymer can include specified amounts of macromonomer and alkyl acrylates. Resulting lubricant compositions can include the comb polymer.

摘要： Systems and methods are provided for estimating the total base number of used oil in an engine. The systems and methods can involve characterizing the sulfur content and at least one other element content of the oil both before introduction into the engine and after passing through an engine cylinder during combustion. Depending on the aspect, a total base number of the oil prior to use can also be measured, or the total base number before use can be estimated based on the at least one element content.

摘要： A lubricant composition comprising an oil of lubricating viscosity and 0.01 to 5 percent by weight of a substantially sulfur-free alkyl phosphate amine salt, where at least 30 mole percent of the phosphorus atoms are in an alkyl pyrophosphate salt structure, exhibits good antiwear performance, even in the presence of corrosion inhibitor additives. In the phosphate amine salt, at least 80 mole percent of the alkyl groups are typically secondary alkyl groups of 3 to 12 carbon atoms.

摘要： The present invention relates to novel quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive; to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct-injection diesel engines, especially in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, especially of diesel engines with common-rail injection systems, and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems.

摘要： A low viscosity oil has more than 50% by weight of 9-methyl-11,13-dioctyltricosane. A lubricating composition having this low viscosity oil as base oil and, optionally, another base oil or an additive. The low viscosity oil has a kinematic viscosity at 100° C., measured by the ASTM D445 standard, of 4 to 8 mm2·s−1. The low viscosity oil can be prepared using a metallocene catalyst, and the low viscosity oil as high performance lubricant can be used for lubrication in the field of motors, hydraulic fluids and gears, in particular bridges and transmissions.
