    摘要: The present invention is related to a hydrocarbon oxidation process. The process comprises bringing one or more hydrocarbons into contact with a source of oxygen in the presence of a radical initiator and a catalyst. The catalyst comprises an organic metal complex located on a catalyst support, and is obtained by partial decomposition of the organic metal complex. For example, the process can be used to produce dimethyl carbonate from dimethoxy methane. The invention is also related to a partially decomposed catalyst that comprises a silica support and an organic metal complex, wherein at least 5% of the organic compound remains in the catalyst. The organic metal complex comprises an organic compound and a metal-based compound wherein the metal is selected from copper, nickel, and combinations thereof. The invention is also related to a process for manufacturing of a catalyst comprising mixing L-arginine, a Cu-based compound, water, and optionally another metal-based compound to form a solution; impregnating the solution onto a silica support to form a catalyst precursor; and partially decomposing the L-arginine to form the catalyst so that at least 5% of L-arginine remains in the catalyst.

    摘要: An interactive television system is provided in which a program listings grid is displayed for the user. The user can scroll in the backwards direction to view information on programs that have been recorded and certain video-on-demand content. Icons or other visual indicators may be provided on program listings screens to indicate the status of the programs. The status information may include an indication of whether programs are available for recording, have been recorded, are being recorded, or will be recorded, or whether a given program is available for advance viewing through the interactive television system's video-on-demand service. Programs can be recorded automatically on user equipment or on network-based equipment. A program may be automatically recorded when a user sets a reminder for the program but fails to watch the program or when a given program is determined to satisfy the user's television viewing preferences.
