  • Publication number: 20240174928
    Abstract: Disclosed is a method for preparing hydrogen-rich fuel gas, including adding aluminum smelting waste residues into medium strong acid and soaking for 2-4 h, filtering and baking an obtained precipitate at 300-400° C. for 3-6 h to obtain pre-treated aluminum smelting waste residues; adding the waste residues into weak acid and performing ultrasonic treatment, performing centrifugal separation on an aluminum ash solution, baking for 3-6 h at a constant temperature of 400-500° C. in an air atmosphere, and naturally cooling to room temperature to obtain a cracking catalyst; uniformly mixing the cracking catalyst and biomass with a mass ratio of 1:1 and adding into a first-stage pyrolyzing furnace under N2 atmosphere, and heating from room temperature to 500-900° C. to obtain first-stage pyrolysis gas; and entering the first-stage pyrolysis gas into a second-stage pyrolyzing furnace for secondary catalytic cracking, so as to obtain hydrogen-rich fuel gas.

  • Patent number: 10620156
    Abstract: The invention discloses a metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor, comprising a three-electrode system composed of a working electrode, a counter electrode, and a reference electrode. The surface of the working electrode is coated with a metal nanoparticles/nanocellulose composites. The surface of the nanocellulose is modified with a strong cationic conducting polymer. The invention promotes the sensitivity and selectivity of glucose sensing with the linear range of 4 ?M-15 mM and the detection limit of 1.4 ?M. Therefore, the sensor possesses high sensitivity, high response speed, stable performance and high anti-interference ability. The preparation method of the metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor is simple and the cost is low. And enzyme is introduced into the preparation process.
