  • Publication number: 20200032151
    Abstract: A coal pyrolysis process device, including a primary coal pyrolysis device and a secondary coal pyrolysis device, wherein a discharge port of the primary coal pyrolysis device communicates with a feed port of the secondary coal pyrolysis device. When coal is in the primary coal pyrolysis device, coal tar is extracted to the maximum extent, and then enters the secondary coal pyrolysis device. The coal continues to be heated and undergo pyrolysis at an upper portion of the secondary coal pyrolysis device, so that volatile matter of upgraded coal having undergone primary pyrolysis and upgrading are further reduced in the secondary coal pyrolysis device, and more gas is produced.

  • Publication number: 20190345455
    Abstract: The present disclosure discloses an alcohol dehydrogenase mutant and application thereof in synthesis of diaryl chiral alcohols, and belongs to the technical field of bioengineering. The alcohol dehydrogenase mutant of the present disclosure has excellent catalytic activity and stereoselectivity, and may efficiently catalyze the preparation of a series of chiral diaryl alcohols in R- and S-configurations. By coupling alcohol dehydrogenase of the present disclosure to glucose dehydrogenase or formate dehydrogenase, the synthesis of chiral diaryl alcohol intermediates of various antihistamines may be achieved. Compared with the prior art, a method for preparing diaryl chiral alcohols through asymmetric catalytic reduction using the alcohol dehydrogenase of the present disclosure has the advantages of simple and convenient operation, high substrate concentration, complete reaction and high product purity, and has great industrial application prospects.

  • Patent number: 10436888
    Abstract: Disclosed is a system and method for a hybrid radar system that integrates frequency-modulated continuous wave (FMCW) mode and interferometry mode. The radar works as a time division system that continuously switches between the FMCW mode and interferometry mode. The FMCW mode is responsible for absolute range detection and the interferometry mode takes cares of the weak physiological movement monitoring. The respective accuracies in range detection and displacement measurement complements the advantages of the two radar modes, providing versatile performance. By steering the antenna beam, the proposed radar system becomes an ideal solution for indoor health care, human localization, and human-computer interaction. Objects or human targets with or without stationary clutters can be precisely located. At the same time, the targets' vital signs and gestures can be monitored.
