  • Publication number: 20180334996
    Abstract: Hybrid rocket motors having fuel grains containing glycidyl azide polymer (GAP) produce high regression rates and can be stopped and restarted. The fuel grains also contain carbon and optionally either hydroxyl-terminated polybutadiene (HTPB) or polyethylene glycol (PEG). TGAP self-deflagration in the hybrid rocket motors is controlled by at least one of motor design and the amount of carbon in the fuel grain.

  • Patent number: 9200235
    Abstract: A method and system for processing algae involves the use of an ionic liquid-containing clarified cell lysate to lyse algae cells. The resulting crude cell lysate may be clarified and subsequently used to lyse algae cells. The process may be repeated a number of times before a clarified lysate is separated into lipid and aqueous phases for further processing and/or purification of desired products.

  • Patent number: 8388846
    Abstract: Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells at lower temperatures than existing algae processing methods. A salt or salt solution is used as a separation agent and to remove water from the ionic liquid, allowing the ionic liquid to be reused. The used salt may be dried or concentrated and reused. The relatively low lysis temperatures and recycling of the ionic liquid and salt reduce the environmental impact of the algae processing while providing biofuels and other useful products.

  • Patent number: 8211307
    Abstract: Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells. The lysate separates into at least two layers including a lipid-containing hydrophobic layer and an ionic liquid-containing hydrophilic layer. A salt or salt solution may be used to remove water from the ionic liquid-containing layer before the ionic liquid is reused. The used salt may also be dried and/or concentrated and reused. The method can operate at relatively low lysis, processing, and recycling temperatures, which minimizes the environmental impact of algae processing while providing reusable biofuels and other useful products.
