  • Patent number: 9694353
    Abstract: A new crystalline zinc (silico)aluminophosphate molecular sieve designated SSZ-90 is disclosed. SSZ-90 is isostructural with the DFO framework type and is synthesized using an ionic liquid as both the solvent and the structure directing agent. The ionic liquid [Q+A?] comprises a cation (Q+) selected from the group consisting of 1,3-diisopropylimidazolium, 1,3-diisobutylimidazolium, and 1-isopropyl-3-isobutylimidazolium and an anion (A?) which is not detrimental to the formation of the molecular sieve.

  • Patent number: 9446998
    Abstract: The present invention relates to a new process which comprises the steps of hydrotreating, paraffin disproportionation and hydroisomerization to convert biological hydrocarbonaceous oxygenated oils comprising triglycerides into biologically-derived paraffinic jet/diesel fuels, solvents and base oils. A combination of conventional hydrogenation/dehydrogenation catalysts, such as Pt/Al2O3, and conventional olefin metathesis catalysts, such as WO3/SiO2, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.

  • Patent number: 9266802
    Abstract: A hydroconversion process comprises contacting a feedstock comprising renewable materials under hydroprocessing conditions with a promoted catalyst selected from a self-supported catalyst, a supported catalyst and combinations thereof, wherein the reaction conditions can be tailored to directly convert the renewable feedstock to the desired product(s) including fatty alcohols, esters, normal paraffins, or combinations thereof. The catalyst comprising at least a Group VIB metal selected from molybdenum and tungsten, a Group VIII metal selected from cobalt and nickel to convert the feedstock into any of fatty alcohols, esters, and normal paraffins. In some embodiments, the process further comprising additional steps to generate various desirable products, including ?-olefins (or PAO, by dehydrating the fatty alcohol products), lubricants and bright stocks (from the oligomerizing of the PAO), and Group 3 lubricants (from co-oligomerizing of the PAO with some short chain olefins).
