A lubricating composition comprising a base oil and one or more additives, wherein the composition has: a sulphated ash content (according to ASTM D 874) of at least 0.4 wt % and at most 1.0 wt. %, by weight of the lubricating composition; a total base number (TBN) value (according to ASTM D 2896) of at least 4.0 mg KOH/g and at most 12 mg KOH/g; a total aromatics content contributed by the base oil in the range from 1 wt % to 30 wt %, by weight of the lubricating composition; and a sulphur content contributed by the base oil of 0.4 wt % or less, by weight of the lubricating composition; and wherein the base oil comprises a blend of (i) a first base oil which is a mineral base oil selected from an API Group I mineral base oil and an API Group II mineral base oil, and mixtures thereof, and (ii) a second base oil selected from an API Group II base oil and an API Group III base oil, preferably wherein the first base oil belongs to a different API group to that of the second base oil.

This disclosure provides a triglyceride oil possessing an extremely low cloud point and low viscosity concomitant with a higher than anticipated saturated fatty acid content, very low polyunsaturated fatty acid content, and low iodine value. While many naturally occurring triglyceride oils possess one or more of these properties, natural triglyceride oils lack one or more of these attributes, thus making them less than ideal in industrial applications, such as lubricants, fuels, or dielectric fluids. The combination of attributes possessed by a triglyceride oil described herein, achieved without the addition of any additives, is unique compared with natural counterparts and as such, can find wide applications in the aforementioned fields.

The present invention relates to drilling fluid comprising one or more linear internal olefin having from 15 to 18 carbon atoms and containing less than 25% branching based on the total amount of the linear internal olefin and a hydrogenated Fischer-Tropsch derived product.

A refrigerator oil composition containing an epoxy compound (X) having at least one of an olefin skeleton and a terpene skeleton, and a base oil (Y).

A refrigerator oil composition containing an epoxy compound (X) having at least one of an olefin skeleton and a terpene skeleton, and a base oil (Y).

Methods are disclosed for producing renewable base oil and a diesel oil from low-value biological oils. Low-value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil by first separating at least part of the saturated free fatty acids from the feedstock and then processing separately this saturated free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed may be processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream.

A number of different branched hydrocarbon compounds (formula I) having a star-like configuration (S) are prepared from renewable oils containing fatty acids or derivatives containing fatty acids. The branched hydrocarbon compounds may be isolated individually or in mixtures, and may be used as part of base oils, such as renewable base oils (RBOs). A process for preparing the branched hydrocarbon compounds of formula I involve conditions that favour a trimerisation reaction followed by hydrotreating conditions. The compounds of formula I may be made by catalytically treating renewable material in a process, and the compounds have desirable qualities relating to lubrication, cold flow as well as having a low Noack volatility.

An object of the present invention is to provide a grease composition which has little influence on the environment and has good rust prevention and water resistance against salt water such as sea water. The grease composition comprises a biodegradable base oil and a rust-preventive agent comprising a calcium sulfonate complex and a sorbitan fatty acid ester, wherein a total content of biodegradable organic substances in the grease composition is 75% by mass or more, and wherein a content of the rust-preventive agent is 2.5 to 30% by mass.

Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.
