    摘要: This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid (i.e. a mixture of liquid hydrocarbon and a hydrogen-containing gas) at a rate insufficient to levitate or ebullate the catalyst bed. Catalyst are selected by density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion, such as in a large pilot plant run, with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed. At the desired flow rate, such catalyst continually flows in a plug-like manner downwardly through the reactor vessel by introducing fresh catalyst at the top of the catalyst bed by laminarly flowing such catalyst in a liquid stream on a periodic or semicontinuous basis. Catalyst is similarly removed by laminarly flowing catalyst particles in a liquid stream out of the bottom of the catalyst bed. Intake for such flow is out of direct contact with the stream of gas flowing through the bed and the flow path is substantially constant in cross-sectional area and greater in diameter by several times than the diameter of the catalyst particles. The catalyst of this invention produces a plug-flowing substantially packed bed of hydroprocessing catalyst which occupies at least about 75% by volume of the reactor volume.

    摘要: A file operations engine is provided that manages many user interactions with their files via a computer system. The operation engine may provide a user with the option to keep both files that have a file name conflict. It may further permit the user to rename a file involved with a file name conflict. The operations engine may also automatically rename one of the files of a file name conflict by appending a character to a root of the filename. The character may include the lowest integer available for the root in a destination for the files. The operations engine may provide the option to keep both files as part of a pre-calculation of potential errors for a requested operation. The operations engine may place file name conflicts in an error queue and permit the user to select an option to keep both files after the conflict is encountered.

    摘要: In a computer system a system of exchanging tokens for queue banks is created that permits a requester to directly specify which queue bank is wanted. Only the desired queue bank is withdrawn from a queue bank repository to accomplish this and no sorting or FIFO handling of queue banks is needed. The system uses a schema similar to a coat check room, where the requester is given a token when the requestor wants to deposit a queue bank into the queue bank repository. The queue bank repository returns the queue bank when the token is returned by the requester. In its most efficient form, two machine-level instructions handle the entire operation, a withdraw instruction and a deposit instruction.

    摘要: A tool management system and interface for a disparate set of data processing tools is disclosed. A main tool menu allows selected tools to be launched so that each tool populates a respective window. A tool is selected by choosing an associated window as the currently-active window. Next, a list of all data items that are available for processing by the tool set may be obtained. A data item that is to undergo processing may be selected. A user interface provides a list of all operations that may be used to process the selected data item, including those operations that are supported by the currently-selected tool, and those operations that are not supported by the selected tool. Following selection of the operation, processing of the selected data item is completed by automatically invoking the appropriate tool.

    摘要: A process-driven object management system for managing data and code modules is disclosed. The object management system includes a repository that stores objects, wherein ones of the objects referred to as “Asset elements” each describe a respective code or data module. The object management system includes a set of scripted tools for performing renovation, transformation, and code development tasks on the code and data modules. According to one aspect of the invention, the tool invocation constructs are stored as objects in the repository, such that some of the same object management tools and automated repository interface functions used to manage the Asset element can also be used to manage and veiw the tool objects.
