    摘要: In a process for converting methane to higher hydrocarbons including aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent stream comprising aromatic hydrocarbons and hydrogen, wherein said first effluent stream comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the hydrogen from said first effluent stream is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent stream having a reduced hydrogen content compared with said first effluent stream.

    摘要: The invention provides a steering column assembly (10) having a first steering column member (12) with an upper end (14) and a mounting feature (16). The mounting feature (16) is operative to support against rotation relative to a vehicle and includes first and second mounting portions (30, 32). The steering column assembly (10) also includes a second steering column member (18) having a lower end (20). The second steering column member (18) is operatively connected to the first steering column member (12) for telescoping movement along a column axis (22). The steering column assembly (10) also includes a first bushing (24) connected to the upper end (14) and disposed between the first steering column member (12) and the second steering column member (18) for supporting the telescoping movement. The steering column assembly (10) also includes a second bushing (26) connected to the lower end (20) and disposed between the first steering column member (12) and the second steering column member (18) for supporting the telescoping movement. The second bushing (26) is disposed between the first and second mounting portions (30, 32) along the column axis (22).

    摘要: A database system is disclosed. The database system includes a common data repository, a document indexing database and a query engine. The common data repository is configured to store data in a common data table and is associated with a data object. The document indexing database is configured to store a data structure model that is associated with a unique document type. The data structure model is configured to facilitate retrieval of data stored in the common data table. The query engine is communicatively linked to the document indexing database and the common data repository. The query engine is configured to use the data structure model to retrieve data from the common data table.
