  • Publication number: 20200369636
    Abstract: The present invention discloses a system and a method for continuously preparing furfural using an acid-containing pentose solution. The system comprises a stripping reaction column, a separation unit, and a purification unit. The method comprises a stripping reaction step, a separation step, and a purification step. The system and the method of the present invention can use a liquid inorganic acid as a catalyst, has a strong catalytic capability and a low reaction temperature, and is capable of treating low concentration sugar liquids. The present invention adopts heating through directly vapor stripping to rapidly carry away a generated furfural along with the vapor while reacting a pentose, avoiding side reactions of the furfural in an acidic liquid environment. The reaction process of the present invention does not require any extracting agent, and the furfural carried away along with the vapor is easy to separate after cooling.

  • Publication number: 20200310739
    Abstract: In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images. If the pause time of pausing satisfies a certain length, a parameter associated with an image compression ratio is adjusted. After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.
