International Classification:
C11D 116 C11D 312
US Classification:
252549
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.

International Classification:
B65G 6906
US Classification:
406119
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.

US Classification:
406136
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.

International Classification:
B65G 5116
US Classification:
406 14
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.

Assignee:
Shell Oil Company - Houston TX
International Classification:
C01J 346 C01K 102
US Classification:
48197R
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.

International Classification:
B65G 5338 B65G 5340
US Classification:
406138
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.
