The present invention relates to a composition of branched fatty acids or esters thereof, the process for preparing such a composition and its use in various industrial fields, such as in lubricant, in cosmetics and in home care. More particularly, the present invention relates to a composition comprising at least 30% by weight of polybranched C.sub.10-C.sub.24 fatty acids or esters thereof, and a cyclic compound content ranging from 1% to 8% by weight, the weight percentage being given on the total weight of the composition.

The present invention relates to a lubricant comprising a liquid ethylene copolymer which comprises in polymerized form 20 to 60 wt % of ethylene; and at least 20 wt % of an acrylate, which is selected from C1-C22 alkyl (meth)acrylate. It further relates to the liquid ethylene copolymer; and to a method for reducing friction between moving surfaces comprising the step of contacting the surfaces with the lubricant or with the ethylene copolymer.

Provided are a lubricating oil composition which contains a base oil (A) containing an ester-based oil (Al), and a polymer (B) having a constituent unit (b) derived from an alkyl (meth)acrylate, wherein the content of the polymer (B) is 0.1 to 10% by mass based on the total amount of the lubricating oil composition, the lubricating oil composition has a viscosity index of 350 or more, the lubricating oil composition has a BF viscosity at −40° C. of 4000mPa.Math.s or less, and the lubricating oil composition is used for an impregnated bearing, and an impregnated bearing impregnated with the lubricating oil composition. The lubricating oil composition has excellent lubricity in use in a wide temperature environment from a low temperature region to a high temperature region, is capable of maintaining excellent infiltration property even in an environment in which a temperature change between a low temperature and a high temperature is severe, and is suitable for use in an impregnated bearing.

A high viscosity lubricant and dispenser for use in machine work. In one example, the lubricant includes avocado oil and has a viscosity that allows it to be dispensed from a twist-up type, or other suitable dispenser as a paste, gel, or semi-solid. In another aspect, the lubricant includes wax to increase viscosity, the wax may be of any suitable type such as, for example, soy wax.

Provided herein are hydrocarbon mixtures with controlled structure characteristics that address the performance requirements for finished lubricants driven by the stricter environmental and fuel economy regulations. The branching characteristics of the hydrocarbon molecules are controlled to provide a composition that has a unique and superior viscosity-temperature relationship and Noack volatility. An important aspect of the present invention relates to a saturated hydrocarbon mixture with at least 80% of the molecules having an even carbon number, with the branching characteristic of BP/BI in the range≥−0.6037 (Internal alkyl branching)+2.0, where on average at least 0.3 to 1.5 of the internal methyl branches are located more than 4 carbons away from the terminal carbon when analyzed by carbon NMR. The saturated hydrocarbon mixture with such unique branching structure consistently exhibits a stand out performance in the cold crank simulated viscosity (CCS) vs Noack volatility relationship, which allows for the formulation of lower viscosity engine oils with improved fuel economies.

Described herein are methods of stabilizing the beta hydrogen of glycerol based esters by the insertion of alkoxy groups to significantly improve the thermal, oxidative, and hydrolytic stability of the ester and allow for controlling the molar density of esters bonds in the lubricants to maximize hydrolytic stability while maintaining biodegradability and further improving performance properties.

Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. In one embodiment, the process comprises selecting waste plastics containing polyethylene and/or polypropylene and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit distillation column in a refinery where a straight run naphtha (C.sub.5-C.sub.8) fraction or a propane/butane (C.sub.3-C.sub.4) fraction is recovered. The straight run naphtha fraction (C.sub.5-C.sub.8) or the propane/butane (C.sub.3-C.sub.4) fraction is passed to a steam cracker for ethylene production. The heavy fraction from the pyrolysis unit can also be passed to an isomerization dewaxing unit to produce a base oil.

A lubricating oil composition includes an ethylene/α-olefin copolymer (A) having 70 to 90 mole % of structural units derived from ethylene and an intrinsic viscosity [η] of 0.3 to 1.0 dl/g.

Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.
