[Abstract]:It is an important research topic in the fields of energy, chemical industry and metallurgy. By analyzing the advantages and disadvantages of the existing gas-solid reaction analysis method and the test instrument, the author proposed a test method for the reaction micro-differentiation and the isothermal analysis under the condition of low diffusion and rapid temperature rise by using the micro-fluidized bed (MFB). The fluid dynamics in the reactor was studied, and a micro-fluidized bed reaction analyzer (MFBRA) was developed to verify and demonstrate the application of typical gas-solid reaction to pyrolysis, combustion (oxidation), gasification, reduction, catalysis, absorption and the like. the micro-fluidized bed reaction analyzer is fully disclosed, the heat and mass transfer of the heat transfer is enhanced, the diffusion suppression is reduced, the characteristic of real-time on-line differential analysis is realized, The research and characterization of the series of gas-solid reaction, such as the series reaction and decoupling, form a gas-solid reaction analysis method and an analyzer which are complementary to the thermogravimetric analysis.
