  • Publication number: 20200239791
    Abstract: Disclosed is a catalytic cracking process for producing isobutane and/or light aromatics in high yield, comprising the steps of: a) providing a catalytic cracking feedstock oil having a polycyclic naphthene content of greater than about 25 wt %; b) subjecting the catalytic cracking feedstock oil to a first catalytic cracking reaction and a second catalytic cracking reaction sequentially under different reaction conditions to obtain a catalytic cracking product; c) separating the resulting catalytic cracking product to obtain a liquefied gas fraction comprising isobutane and a gasoline fraction comprising light aromatics; and d) optionally, recovering isobutane from the liquefied gas fraction and/or recovering light aromatics from the gasoline fraction. The process can enable the production of isobutane and/or light aromatics in high yield.

  • Publication number: 20190140927
    Abstract: This application discloses a service chain fault detection method and an apparatus. The method includes: determining, by a service forwarding entity (SFE), to communicate with a first service function (SF) node on a service chain after obtaining a first fault tracing detection request packet, wherein the first fault tracing detection request packet comprises a path identifier (ID), and the path ID is used to identify a path of the service chain; obtaining, by the SFE, an ID of the first SF node; and sending, by the SFE, a first fault tracing detection response packet to the device for initiating fault detection, wherein the first fault tracing detection response packet comprises the path ID and the ID of the first SF node.

  • Patent number: 10263901
    Abstract: The present invention discloses a service packet processing method, apparatus, and system. The method includes a first service atom receiving a second packet sent by a central switching device, where a first service packet is encapsulated in the second packet and the second packet further includes a first service path identifier. The first service atom performs first service processing according to information in the first service packet, to obtain a first processing result. The first service atom queries a first path switching entry according to the first processing result and the first service path identifier. The first service atom sends a third packet to the central switching device, where a source device identifier of the third packet is a device identifier of the first service atom, a second service packet is encapsulated in the third packet, and the third packet includes the second service path identifier.
