  • 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.

  • Patent number: 10047263
    Abstract: The present invention generally relates to a method for manufacturing phase change material (PCM) pellets. The method includes providing a melt composition, including paraffin and a polymer. The paraffin has a melt point of between about 10° C. and about 50° C., and more preferably between about 18° C. and about 28° C. In one embodiment, the melt composition includes various additives, such as a flame retardant. The method further includes forming the melt composition into PCM pellets. The method further may include the step of cooling the melt to increase the melt viscosity before pelletizing. Further, PCM compounds are provided having an organic PCM and a polymer. Methods are provided to convert the PCM compounds into various form-stable PCMs. A method of coating the PCMs is included to provide PCMs with substantially no paraffin seepage and with ignition resistance properties.
