The reaction is carried out in water at a temperature range of 120-300° C., with a hydrogen pressure range of 1-13 MPa. Compared with the present petroleum based synthesis technology of ethylene glycol, the method in this invention possesses advantages of using renewable feedstock, high atom economy and environmental friendly.

  • Publication number: 20200153658
    Abstract: A tunnel establishment method and apparatus is disclosed. Even if an entity for executing the solution is not changed, a type of a tunnel established for each service of a terminal may be the same or may be different. For example, a first tunnel and a second tunnel may be established for a current service of the terminal, and a third tunnel may be established for a next service of the terminal. This eases congestion in a backbone network between a secondary access network node and a primary access network node. Alternatively, this avoids using a directly connected tunnel as a tunnel established between the secondary access network node and a core network user plane node when a core network control plane node needs to receive and send too much path switching signaling.

  • Patent number: 10645725
    Abstract: Embodiments of the present invention provide a method that includes: A network device and a terminal device determine a backoff time for a current frame, performs a CCA based on the backoff time, obtains an assessment result of the CCA, and sends a pilot when the assessment result of the CCA is that a channel is in an idle state; the terminal device listens on the channel based on the backoff time, and sends or receives data over the channel after detecting the pilot sent by the network device. This resolves a problem that a large quantity of electricity is wasted because the terminal device needs to keep listening on the channel when the network device is in an LBT process. The terminal device listens on the channel based on the backoff time; in another time period, the terminal device does not listen and may enter a sleep state.
