  • Patent number: 8558042
    Abstract: 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.

  • Publication number: 20130053525
    Abstract: The present disclosure is directed to the production of substituted phenylene aromatic diesters and 5-tert-butyl-3-methyl-1,2-phenylene dibenzoate (or “BMPD”) in particular. The processes disclosed herein produce a liquid BMPD product. The liquid BMPD product unexpectedly creates production efficiencies by reducing the number of production steps, reducing the amount and/or number of reagents required for BMPD production. The liquid BMPD product may also be utilized in procatalyst production yielding similar production efficiencies. The procatalyst composition is subsequently used for olefin polymerization.

  • Publication number: 20120251424
    Abstract: A process for producing a hydrocarbon from biomass. A feed stream containing biomass having fatty acids, mono-, di-, and/or triglycerides, and a phosphorus content of between about 1 wppm and about 1,000 wppm is provided. A heated hydrocarbon solvent and a hydrogen-rich gas are provided. The feed stream, the heated hydrocarbon solvent, and the hydrogen-rich gas are combined in the presence of a low activity hydrogenation catalyst. A spent low activity hydrogenation catalyst is recovered at the end of a run wherein the spent low activity hydrogenation catalyst contains at least 3% by weight phosphorus.
