Proposed is a process of producing a high-quality lube base oil using a refined oil fraction obtained from waste lubricant as a feedstock. The process includes purifying waste lubricant to obtain a refined oil fraction, pretreating the refined oil fraction, and blending the pretreated refined oil fraction with unconverted oil (UCO), before or after vacuum distillation and catalytic dewaxing of the unconverted oil, or between the vacuum distillation and the catalytic dewaxing of the unconverted oil.

Process of producing high-quality lube base oil by using refined oil fraction of waste lubricant

Proposed is a mineral lubricating base oil having improved low-temperature performance, in which the lubricating base oil has kinematic viscosity of 9.0 cSt or less (at 40&#xb0; C.), kinematic viscosity of 2.5 cSt or less (at 100&#xb0; C.), and a pour point of &#x2212;50&#xb0; C. or less.

Mineral base oil having improved low temperature property, method for manufacturing same, and lubrication oil product comprising same

Disclosed is a method of producing a lubricating base oil, including providing a feedstock including a diesel fraction, subjecting the feedstock to catalytic dewaxing, and recovering a lubricating base oil from a product of the catalytic dewaxing. A lubricating base oil produced thereby and a lubricant product including the lubricating base oil are also provided.

Method of producing lubricating base oil from feedstock comprising diesel fraction, and lubricating base oil produced thereby

Disclosed is a method of manufacturing high-quality lube base oil, by converting a low-value linear alpha-olefin having a C18 or more hydrocarbon chain into a linear internal-olefin having a controlled double bond position distribution and then oligomerizing the linear internal-olefin.

Method of upgrading low-value linear alpha-olefins of C18 or more

Disclosed is a method for producing a quality lubricant base oil (meeting the standard of Group III or higher) comprising: decarbonylating mixed fatty acids derived from oils and fats of biological origin to produce mixed olefins; oligomerizing the mixed olefins to produce an olefinic lubricant base oil; and performing hydrogenation to remove olefins from the olefinic lubricant base oil.

Method for preparing high-quality lubricant from biomass-derived fatty acid

Disclosed is a method of preparing a drilling fluid and lube base oil using biomass-derived fatty acid, including hydrogenating a fatty acid mixture derived from fat of biological origin so as to be converted into a fatty alcohol mixture, which is then dehydrated to give a C16 and C18 linear internal olefin mixture, which is then oligomerized to give olefinic lube base oil, followed by hydrofinishing to remove the olefin, yielding high-quality lube base oil (e.g. Group III or higher lube base oil). The C16 and C18 linear internal olefin mixture, which is a reaction intermediate, can be utilized as a high-quality drilling fluid.

Method of preparing drilling fluid and lube base oil using biomass-derived fatty acid

A method for preparing an estolide compound and an estolide compound prepared thereby are disclosed. The method for preparing an estolide compound includes: converting biomass fat into a fatty acid; separating the fatty acid into a Csaturated fatty acid and a Cunsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the Cunsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the Csaturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.

Estolide compound and method for preparing the same

A method for preparing a ketone group-containing estolide compound and a ketone group-containing estolide compound prepared thereby are disclosed. The method for preparing a ketone group-containing estolide compound includes converting biomass fat into a fatty acid; separating the fatty acid into a C16 saturated fatty acid and a C18 unsaturated fatty acid; increasing an amount of oleic acid through partial hydrogenation of the C18 unsaturated fatty acid; synthesizing a C35 ketone through ketonization of the oleic acid; and performing estolide bonding by capping the C16 saturated fatty acid onto the C35 ketone.
