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% C 7 -C 12 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.
Abstract:
The present disclosure relates to biofuels, and more particularly, to biomass-based kerosene and aviation turbine fuels. In an aspect, a method is disclosed for producing a light paraffinic kerosene (LPK) where the method includes hydrotreating a biorenewable feedstock to yield a heavy hydrotreater fraction comprising C14-C24 n-paraffins; hydroisomerizing and hydrocracking the heavy hydrotreater fraction with a hydroisomerization catalyst under conditions yielding a hydroisomerizer product that includes a heavy hydroisomerizer fraction and the LPK; and separating the LPK from the hydroisomerizer product. The LPK provided by the method has an existent gum value of 7 mg/100 mL or less as measured according to IP 540 air evaporation method and further includes (a) a weight ratio of isoparaffins to n- paraffins of about 2: 1 or greater, or (b) no detectable hydrocarbons with 14 or more carbon atoms as measured by gas chromatography, or (c) a weight ratio of isoparaffins to n-paraffins of about 2: 1 or greater and no detectable hydrocarbons with 14 or more carbon atoms as measured by gas chromatography.
Abstract:
The present technology provides a method to produce hydrocarbon renewable fuels. The method includes hydrodeoxygenating a feed to produce a hydrocarbon product, where the feed includes fatty alcohols and the hydrocarbon product includes C 10 -C 12 n-paraffins and a heteroatom oxygen content less than 0.1 wt%.
Abstract:
The present technology relates to hydrocarbon fuels comprising renewable content. More particularly, the technology relates to manufacture of renewable diesel for potential use as aviation turbine fuel blendstock.
Abstract:
The present technology provides a method that includes contacting a composition with a caustic solution to produce a caustic-treated composition; combining the caustic-treated composition with silica particles to produce a slurry; and removing the silica particles from the slurry to produce a treated composition; wherein the composition includes one or more of animal fats, animal oils, plant fats, plant oils, vegetable fats, vegetable oils, greases, and used cooking oil and the composition includes: at least about 10 wppm of total metals, at least about 8 wppm of phosphorus, at least about 10 wppm of chlorine, at least about 10 wppm of sulfur, at least about 20 wppm of nitrogen, at least about 5 wt.% of free fatty acids; and has an acid number from about 10 mg KOH/g to about 150 mg KOH/g, and the silica particles has a particle size from about 10 microns to about 50 microns, a BET surface area from about 200 m 2 /g to about 1000 m 2 /g.
