  • Patent number: 10021114
    Abstract: A server computer receives an indication of an interaction between a first user device of a first user and a second user device of a second user, where the interaction includes a message for transmission from the first user to the second user. The server computer performs a verification process on the message, including performing one or more binary checks on the message. The server computer then generates a response indicating whether the message is a legitimate message based on the verification process. When the response indicates that the message is a legitimate message, the server computer transmits the message to the second user device of the second user for display.

  • Publication number: 20180171239
    Abstract: A process is provided for determining the suitability of pyrolysis tar, such as steam cracker tar, for upgrading using hydroprocessing without long term fouling of the hydroprocessing reactor. The process includes heating a sample of the tar, quenching the sample, and measuring the total free radical content of the quenched sample. A pyrolysis tar can be blended with one having a lesser total free radical content to produce a blend that can be hydroprocessed with decreased fouling.
