Provided herein is an e-Drive fluid containing PAO 2.5, ester and hydrocarbon mixtures with controlled structure characteristics that address the performance requirements for film thickness and efficiency within e-transmissions.

An electrotechnical fluid composition, comprising more than 90 wt-% paraffins in the C17-C18 range, based on the total weight of the composition, is described. The ratio of the amount of C18 i-paraffins to the amount of C18 n-paraffins is more than 40, based on the weight of the C18 i-paraffins and the weight of the C18 n-paraffins in the composition.

A dielectric nanolubricant composition is provided. The dielectric nanolubricant composition includes a nano-engineered lubricant additive dispersed in a base. The nano-engineered lubricant additive may include a plurality of solid lubricant nanostructures having an open-ended architecture and an organic, inorganic, and/or polymeric medium intercalated in the nanostructures and/or encapsulate nanostructures. The base may include a grease or oil such as silicone grease or oil, lithium complex grease, lithium grease, calcium sulfonate grease, silica thickened perfluoropolyether (PFPE) grease or PFPE oil, for example. This dielectric nanolubricant composition provides better corrosion and water resistance, high dielectric strength, longer material life, more inert chemistries, better surface protection and asperity penetration, no curing, no staining, and environmentally friendly, compared to current products in the market.

A sliding surface, which is formed using metal (SUJ2, palladium etc.) or oxide ceramics (ZrO.sub.2), is made to slide, at a Hertzian contact stress of 1.0 GPa or more in an atmospheric environment containing a hydrogen gas including a minute amount of an alcohol and water, against a slid surface including a PLC film which is a coating formed by an ionization deposition method while applying a low bias voltage. Consequently, it is possible to form, on the sliding surface, a low-friction coating that stably exhibits a significantly low friction coefficient of 10.sup.−4 order (less than 0.001).

The disclosure relates to an electrocrushing drilling fluid with an electrocrushing drilling base fluid including a non-polar oil, water, and glycerin. The base fluid may further include a polar oil and an alkylene carbonate. The electrocrushing drilling fluid may further contain at least one additive. The electrocrushing drilling fluid may have a dielectric constant or dielectric strength of at least a set amount, an electric conductivity less than a set amount, or a combination of these properties. The disclosure further relates to an electrocrushing drilling system containing the electrocrushing drilling fluid and an electrocrushing drill bit.

A process to convert paraffinic feedstocks into renewable poly-alpha-olefins (PAO) basestocks. In a preferred embodiment of the invention, renewable feed comprising triglycerides and/or free fatty acids are hydrotreated producing an intermediate paraffin feedstock. This paraffin feedstock is thermally cracked into a mixture of olefins and paraffins comprising linear alpha olefins. The olefins are separated and the un-reacted paraffins are recycled to the thermal cracker. Light olefins preferably (C2-C6) are oligomerized with a surface deactivated zeolite producing a mixture of slightly branched oligomers comprising internal olefins. The heavier olefins (C6-C16) are oligomerized, preferably with a BF3 catalyst and co-catalyst to produce PAO products. The oligomerized products can be hydrotreated and distilled together or separate to produce finished products that include naphtha, distillate, solvents, and PAO lube basestocks.

Provided herein are methods for producing α,β-unsaturated ketones from the condensation of methyl ketones in the presence of an amine catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The α,β-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such α,β-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.

A process to make an isoalkane alkylate base oil, comprising: a. oligomerizing an olefin feed having a carbon number from 3 to 6 using a metallocene catalyst to make an unsaturated olefin oligomer; and b. alkylating an isoalkane feed with the unsaturated olefin oligomer in the presence of an acidic alkylation catalyst, and without any addition of hydrogen, to make an alkylate product comprising the isoalkane alkylate base oil having a kinematic viscosity at 100° C. greater than 10 mm.sup.2/s, a VI higher than 80, and a bromine index less than 1000 mg Br/100 g.

A process to make an alkylate base oil having a viscosity index greater than or equal to 90, comprising: a. converting an at least one dimeric ketone to an at least one alcohol; b. dehydrating the at least one alcohol to make one or more corresponding olefins; and c. alkylating at least one isoalkane with the one or more corresponding olefins to form the alkylate base oil.

A water-soluble lubricant composition for warm and hot plastically working of an aluminum material comprising (A) hydrophilic polyester resin, (B) alkali metal salt of a polymaleic acid resin, (C) alkali metal salt of carboxylic acid and (D) water, and optionally (E) a wax.
