When choosing synthetic oil over regular mineral oil it's worth remembering that mineral oils have been around for a long time and function very well as lubricants in most industrial applications. Now this recent news from Amyris is pretty interesting since I used to cover a little bit of the base oil industry when I wrote articles for Chemical Market Reporter before on lubricants, greases and waxes. In lubricating oils, this wax is removed in a refining process called dewaxing. [0018] (3) Wax obtained by a lubricating oil dewaxing step (slack wax or the like) and/or synthetic wax obtained by a gas-to-liquid (GTL) process (Fischer-Tropsch wax, GTL wax or the like). Poor oxidation stability at Synthetic base oils are expensive because of the processing involved in creating these pure chemical base oils. €�This new base oil is another clear example of Shell Lubricants' commitment to using In the last step of the process, the waxes are cracked and distilled into finished GTL products. Most products of Crude oil processing are usually grouped into three categories: light distillates (LPG, gasoline, naphtha), middle distillates (kerosene, diesel), heavy distillates and residuum (fuel oil, lubricating oils, wax, tar). €�The arrival of the first shipment of GTL base oil to the Americas is an extremely exciting event for Shell Lubricants and our customers,” said Lisa Davis, president, Shell Commercial Fuels and Lubricants, Americas. GreenMantra's catalytic depolymerization process converts recycled plastics into industrial products such as waxes, greases and lubricating oils. This process again produces two products: a byproduct wax that is almost completely paraffinic and a dewaxed oil that contains paraffins, naphthenes and some aromatics. You have to separate the different types of hydrocarbons to have anything useful. They are cost-effective and The presence of waxes, which can result in poor flow properties at low temperature. There are those who claim a waxed chain will not last as long as a chain lubricated with modern synthetic oils (probably the manufacturers of those products), but anecdotal evidence seems to support the contrary. This classification is based on the way crude oil is distilled and separated into fractions (called distillates and residuum) as can be seen in the above drawing.
