  • Secondary alkyl sulfate/zeolite-containing surfactant compositions
    Patent number: 5427717
    Abstract: This invention relates to solid secondary alkyl sulfate/zeolite-containing surface active compositions which are formed by crystallization and which contain at least about 80 percent by weight of secondary alkyl sulfate and zeolite. These compositions are substantially free of unreacted organic matter and water. The invention further relates to a process for preparing these solid secondary alkyl sulfate/zeolite-containing compositions.
    Type: Grant

  • Aeration tube discharge control device
    Patent number: 5129766
    Abstract: The invention is directed to a method and apparatus for establishing and maintaining a uniform mass flow rate of particulate solids and gas mixture from a container to a receiving reactor. A preferred embodiment utilizes an aeration tube suspended in the particulate mixture and serving as a fluidic valve to maintain a uniform mass flow rate. A portion of the aeration gaseous fluid may be directed upward in aid of such flow.
    Type: Grant

    Date of Patent: July 14, 1992
    Assignee: Shell Oil Company
    Inventors: Hendricus A. Dirkse, Johannes E. G. Ploeg, Rene Rombout, Rudi Everts, Andrew M. Scott, Thomas S. Dewitz, Charles M. Arbore, Uday Mahagaokar
  • Aerated discharge device
    Patent number: 5106240
    Abstract: The invention is directed to a method and apparatus for establishing and maintaining a uniform mass flow rate of particulate solids and gas mixture from a container to a receiving reactor. A preferred embodiment utilizes a plurality of porous inserts in the walls of the container through which a gaseous fluid is forced thereby contacting particulate solids within said container and enhancing the flow of said solids.

  • Process for flyslag treatment utilizing a solids-containing concentrated aqueous stream
    Patent number: 4969933
    Abstract: A process for the treatment of flyslag from the gasification of coal is described, the process being characterized, in one embodiment, by mixing of the flyslag with a residual waste stream from a coal gasification process, the wast stream containing particulate flyslag solids.
    Type: Grant

    Inventors: Edward H. Hsu, Daniel C. Baker, Charles M. Arbore
  • Feed hopper design
    Patent number: 4869622
    Abstract: The present invention is directed to an apparatus and method for equalizing the flow rate of a combustible, particulate solids, such as coal, and gas mixture discharged from a feed vessel apparatus in a uniform manner to a pressurized receiving reactor, such as a gasifier.
    Type: Grant
    Filed: September 18, 1987
    Date of Patent: September 26, 1989
    Assignee: Shell Oil Company

  • Pressure compensated weigh system
    Patent number: 4838738
    Abstract: The present invention is directed to an apparatus and method for controlling mass flow rate of a particulate solids and gas mixture to a reactor. In particular, the fast response of a mass flow rate-indicating device is combined with the longer term accuracies in changes in the total mass from weigh cells to yield rapid and more accurate loss-in-weight measurements than conventional systems.
