Latest Patents

One of her latest patents is titled "Hydrotreating olefin stream with complete destruction of oxygenates." This patent discloses a process for completely destroying oxygenates in a feed stream, which typically includes olefins. The process involves reacting the feed stream with hydrogen over a catalyst that comprises a top row of Group VIII metal and a Group VI-B metal. The olefins are essentially completely saturated, and any sulfur compounds present in the feed are completely converted to hydrogen sulfide. A preferred catalyst includes 2 to 5 wt-% nickel, 5 to 15 wt-% molybdenum, at least 5.5 wt-% sulfur, less than 0.05 wt-% phosphorus, and no more than 0.3 wt-% silicon. The catalyst has low acidity, which prevents the cracking of desired oligomeric products. The deoxygenation process is preferably a saturation process that follows an oligomerization process, where light olefins are oligomerized to heavy olefins.

Another notable patent is "Chromatographic separation of fatty acids using ultrahydrophobic." This patent describes a method for creating silicalite with increased hydrophobicity by steaming it in an atmosphere of at least 10% water vapor at temperatures of 650-850°C. When used as monodisperse spheres with a diameter ranging from 1-20 microns, this ultrahydrophobic silicalite serves as an excellent adsorbent for chromatographic separation of polar materials, including fatty acids, at both analytical and preparative levels using simulated moving bed techniques.
