  • Self-ignition resistant thermally-activated carbon
    Patent number: 9358523
    Abstract: Thermally-activated cellulosic-based carbon is rendered more thermally stable by exposure to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100° C. to about 420° C.
    Type: Grant
    Filed: October 15, 2014
    Date of Patent: June 7, 2016
    Assignee: Albemarle Corporation
    Inventors: Jonathan P. O'Dwyer, Qunhui Zhou, Gregory H. Lambeth, Yinzhi Zhang, Christopher J. Nalepa
  • Brominated sorbents for removing mercury from emissions produced during fuel combustion
    Patent number: 9089834
    Abstract: Activated cellulosic-based carbon is rendered more thermally stable by exposure to water or aqueous acid, and optionally, to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon has enhanced thermal properties and is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100° C. to about 420° C.

  • System for multilevel secure database management using a knowledge base with release-based and other security constraints for query, response and update modification
    Patent number: 5355474
    Abstract: Apparatus for an integrated architecture for an extended multilevel secure database management system. The multilevel secure database management system processes security constraints to control certain unauthorized inferences through logical deduction upon queries by users and is implemented when the database is queried through the database management system, when the database is updated through the database management system, and when the database is designed using a database design tool.
