  • Patent number: 8883036
    Abstract: A process for the production of a H2S-enriched H2 gas stream without the need for H2S compression is disclosed. A slip stream of rich amine from a hydroprocessing unit is reduced in pressure and stripped with a hydrogen-containing gas. The H2S content of the resulting gas stream can be readily controlled by adjusting the stripping pressure and/or hydrogen rate. The H2S-enriched H2 gas stream is suitable for the sulfidation of catalytically active metals.

  • Patent number: 8809222
    Abstract: An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. In the process, high shear mixing is employed to generate an emulsion containing droplets of metal precursor in oil with droplet sizes ranging from 0.1 to 300 ?m. The emulsion is subsequently sulfided with a sulfiding agent, or in-situ in a heavy oil feedstock to form a slurry catalyst. The in-situ sulfidation in heavy oil is under sufficient condition for the heavy oil feedstock to generate the sulfiding source needed for the sulfidation.

  • Publication number: 20120265617
    Abstract: A system for automatically measuring the size of a radio or television audience at any particular time is provided. In the system, a remote computer may identify the broadcast stations to which listening devices, such as radios or televisions, are tuned. To identify the broadcast stations, the remote computer commands the listening device instructing/commanding the listening device to poll its radio receiver tuner to determine the frequency it is tuned to. This information is then transmitted from the listening device to the remote computer where it may be used to determine what broadcast station the listening device is tuned to. This data is then stored and accumulated, so that over time the listening habits of the user may be identified. The collected data may be used by broadcast stations to determine the cost of advertisements. Additionally, the system provides for the monetization of advertising by charging advertisers for downloads.
