  • Polymers and membranes for separation of polar organic compounds from aqueous mixtures and methods of using
    Patent number: 10086339
    Abstract: A polymer having a contact angle with water that is greater than or equal to 90° and a contact angle with 1,3-propane diol that is less than 90°. A pervaporation membrane comprising the polymer and a process for purifying a fermentation broth using a pervaporation membrane comprising the polymer is also described.
    Type: Grant

    Assignee: THE UNIVERSITY OF CONNECTICUT
    Inventors: Richard Steven Parnas, Alexandru Asandei, Baishali Kanjilal, Iman Noshadi
  • Process for converting fats, oils and greases into fuels
    Patent number: 9701911
    Abstract: A method for producing a light oil fraction from plant-based and/or animal-based fats, oils or greases is disclosed. The method comprises introducing a feedstock including free fatty acids into a processing system. The system is heated at a controlled rate to a specified temperature, both of which are selected to produce a light oil fraction with a reduced fatty acid content. The system is permitted to reflux for a predetermined time, during which more of the light oil fraction is produced. The light oil fraction is separated from the remainder of the feedstock and contains less than 10% free fatty acids.
