  • Publication number: 20210261875
    Abstract: The present technology provides compositions that include at least about 98 weight percent (“wt %”) n-paraffins which, among other surprising features, may be suitable for use as a diesel fuel, an aviation fuel, a jet fuel blendstock, a blendstock to reduce the cloud point of a diesel fuel, a fuel for portable heaters, and/or as a charcoal lighter fluid. The composition includes at least about 98 wt % C7-C12 n-paraffins, where at least about 10 wt % of composition includes n-decane, at least about 20 wt % of the composition includes n-dodecane, and at least about 75 wt % of the composition includes even carbon number paraffins. The composition also includes less about 0.1 wt % oxygenates and less than about 0.1 wt % aromatics. The composition may be produced by a process that includes hydrotreating a biorenewable feedstock comprising at least one of palm kernel oil, coconut oil, babassu oil, microbial oil, or algal oil.

  • Patent number: 11078427
    Abstract: A process for producing crude biodiesel from renewable feedstocks (such as fats, oils, and greases) containing unsaponifiable materials; purifying the crude biodiesel through a purification process; recovering a purified biodiesel distillate stream and a less volatile biodiesel residue stream; and further recovering valuable chemicals from the biodiesel residue. Specifically, the present technology relates to the concentration of valuable chemicals in the biodiesel residue product of biodiesel production and the subsequent recovery of these valuable chemicals. The process may further include the conversion of the biodiesel residue into diesel range hydrocarbons using hydrodeoxygenation and the subsequent purification of the hydrocarbon fraction produced thereby.

  • Publication number: 20210038998
    Abstract: Embodiments of the systems and methods disclosed herein provide a gaming console and gaming controllers, including hardware and software features included on the hardware. For example, a game balancing system is described that can monitor and track performance data from one or more players of the gaming console. With the performance data, artificial intelligence and machine learning can be used to create one or more models that are applied to determine adjustments to games being played on the gaming console. The adjustments to the games can be implemented specifically to each game, player, or set of players to achieve more balanced gameplay as measured by game outcomes and other factors.

  • Patent number: 10450533
    Abstract: Methods and devices for economically producing a purified biodiesel product from feedstocks. Some embodiments of the methods comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The crude biodiesel is then subjected to at least one biodiesel refining process which, in conjunction with feedstock pretreatment and free fatty acid refining produces a purified biodiesel product that meets multiple commercial specifications. A wide variety of feedstocks may be used to make biodiesel that otherwise would not meet the same commercial specifications, including corn oil, used cooking oil, poultry fats, fatty acid distillates, pennycress oil, and algal oils.

  • Patent number: 9909077
    Abstract: The present invention provides a method for producing a refined fatty acid alkyl ester (FAAE) product from feed-stocks containing free fatty acids. The method comprises glycerolysis and transesterification processes combined with end-product refining. Products produced from a transesterification reaction are separated into a crude FAAE stream and a crude glycerin stream. The crude glycerin stream is further processed to produce a glyceride stream from which additional FAAEs may be produced.

  • Publication number: 20150321419
    Abstract: The invention, and all of its embodiments, is a 3-D printer that utilizes one or more extrusion screws to process any given material including, but not limited to, plastic, metal, composites and non-metals to build 3-dimensional objects. The processed material is deposited on a moveable platform via force from the extrusion process. Motion is numerically controlled via a computer and one or more motors. As the extruder deposits material, a platform or the extruder is moved in one, two, or three dimensions at a predetermined vector. Once a layer of the object is created, the distance between the extruder nozzle and print surface is increased and the process is repeated until a three dimensional shape is created.

  • Publication number: 20150158806
    Abstract: Methods, processes, apparatus, equipment and systems are disclosed for converting carboxylic acids into esters by esterification with alcohol and a dual catalyst. The method combines a homogenous and heterogeneous catalyst in one or more reactors to increase the conversion of carboxylic acids compared to using a homogenous and/or heterogeneous catalyst independently. The invention converts free fatty acids into esters by esterification with alcohol and a dual catalyst such that the reaction mixture contains sufficiently low free fatty acids and the amount of free fatty acids in the product stream leaving the process remains stable over time.
