摘要： 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.

摘要： Biological compositions containing animal fats and plant oils desirably are free of contaminants prior to processing into a biofuel. Disclosed herein is a method of removing such contaminants from these compositions to make that processing more efficient. The method employs a unique arrangement of mixers and centrifuges along with acidic solutions and recycle streams to remove these contaminants from the compositions.

摘要： The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.
