Abstract: Provided is a lubricating oil composition including a lubricating oil additive and a lubricating oil, the lubricating oil additive having nanodiamonds, of which a surface is hydrophobically modified by a surface treatment, dispersed in a base oil. The lubricating oil composition retains dispersibility over a long period of time and thus can ensure storage stability. Machines to which the lubricating oil composition is applied may have improved abrasion resistance as well as improved fuel consumption and reduced noise, and high thermal conductivity of the lubricating oil composition may also increase cooling efficiency and the service life of machines.

Abstract: A method for production of renewable hydrocarbons, including alpha olefins, renewable diesel, synthetic gasoline, and acyl-glycerides, from renewable oils is described herein. Also included is a method for production comprising (a) blending a specific renewable oil mixture with the proper free fatty acid character; (b) acid hydrolysis of the free fatty acids and subsequent purification of the unsaturated and saturated chains; (c) converting the saturated portion into renewable diesel; and (d) reacting the unsaturated free fatty acids via ethenolysis to form alpha olefins, then converting the remaining free fatty acids into either synthetic gasoline or into an acyl-glycerol via glycerolysis.
