  • Patent number: 10670598
    Abstract: The present invention discloses a preparation method of Cryptococcus neoformans capsular polysaccharide GXM as well as a GXM antigen immunoassay kit and an application thereof. The preparation method of the Cryptococcus neoformans capsular polysaccharide GXM effectively avoids the use of a toxic chemical reagent, ensures safety of operators, and also avoids environmental pollution, has high specificity, and can prepare a high-purity Cryptococcus neoformans capsular polysaccharide while simplifying a preparation process. The GXM antigen immunoassay kit adopts a competition method, has good sensitivity, specificity, repeatability and stability, has high recovery rate of a target compound and may provide more accurate and reliable inspection results. The kit is simple and feasible in use and operation, rapid and sensitive in detection and low in price and provides an effective tool for clinical detection of GXM.

  • Patent number: 10253263
    Abstract: The invention belongs to the field of biomass energy utilization, and a continuous pyrolysis and carbonization method of agricultural and forestry biomass is disclosed. The method comprises the following steps: feeding biomass feedstock to a dryer for drying, then transporting to a continuous pyrolysis apparatus for pyrolyzing to obtain pyrolysis semicoke and pyrolysis volatiles; and transporting the pyrolysis semicoke to a carbonization apparatus for carbonization to obtain biomass charcoal and semi-coke carbonized volatiles; then discharging the pyrolysis volatiles and the semi-coke carbonized volatiles, and cooling to obtain tar, wood vinegar and pyrolysis gas; introducing the pyrolysis gas into a combustion apparatus for combustion to obtain a high temperature flue gas; and finally transporting the high temperature flue gas into pyrolysis apparatus and carbonization apparatus for supplying heat, then the flue gas after supplying heat is delivered to the dryer and discharging tail gas.
