【摘要】：准确测试气-固反应特性、求算动力学参数和推导反应机理是能源、化工、冶金等过程工程领域的重要研究课题。通过分析现有气-固反应分析测试方法与测试仪器优缺点,本文作者提出了利用微型流化床(MFB,micro fluidized bed)实现低扩散、快速升温条件下的反应微分化和等温分析的测试方法,系统研究了反应器内的流体力学特性,研制了微型流化床反应分析仪(MFBRA,micro fluidized bed reaction analyzer),验证和展示了其对热解、燃烧(氧化)、气化、还原、催化、吸收等典型气-固反应的应用,充分揭示了微型流化床反应分析仪强化传热传质、降低扩散抑制、实现实时在线微分分析的特性,尤其为快速复杂反应提供了有效的研究分析手段,并且拓展了水蒸气气氛、在线颗粒采样、串联反应解耦等系列气-固反应研究与表征功能,形成了与热重分析互补的气-固反应分析方法和分析仪。
[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.
