  • Publication number: 20210222075
    Abstract: A process for treatment of PFO from a steam cracking zone includes selectively hydrogenating PFO or a portion thereof for conversion of polyaromatics compounds contained in the PFO into aromatic compounds with one benzene ring to produce a selectively hydrogenated stream. The selectively hydrogenated stream is selectively hydrocracked for selective ring opening and dealkylation to produce a selectively hydrocracked BTX+ stream. The selectively hydrocracked BTX+ stream is separated into BTX compounds. Optionally the PFO is separated into a first stream containing C9+ aromatics compounds with one benzene ring, and a second stream containing C10+ aromatic compounds, whereby the first stream containing C9+ aromatics compounds with one benzene ring is passed to the selective hydrocracking step, and the feed to the selective hydrogenation step comprises all or a portion of the second stream containing C10+ aromatic compounds.

  • Patent number: 11070886
    Abstract: The embodiments of the present application provide a method and an apparatus for releasing a video file, which are applied to a server. The method comprises obtaining a video file to be released; selecting a first preset number of video frames in the video file to be released; generating a target video file from the selected video frames, determining a target display position in a video preview interface for the target video file; and saving a correspondence between the target display position and the target video file such that a first terminal logging in the server can play the target video file at the target display position in the video preview interface based on the correspondence. As can be seen, since the first terminal plays the target video file at the target display position in the video preview interface, the user can get more information about contents of the video file to be released from the target video file, which improves user experience.

  • Publication number: 20210218740
    Abstract: Embodiments of the present disclosure provide a method and a device for cross-domain strong logically isolation and secure access control in the Internet of Things (IoT). The method includes the following. When one IoT gateway receives the identity authentication request, the IoT gateway sends the identity authentication request to all IoT gateways in the domain excluding that IoT gateway. When all IoT gateways in the domain receive the identity authentication request, all IoT gateways verify separately whether the identity authentication request is legal. After a certain IoT gateway obtains the identity authentication result, a distributed consensus procedure is initiated. The IoT gateways in the domain reach a consensus on the identity authentication result through a distributed consensus mechanism, and the identity authentication result is written and stored to a block of a blockchain.
