Thermal Analysis Approach and Instrument for Non-catalytic Gas-solid Reactions
摘要
Abstract
It is critical to accurately measure the near-intrinsic reaction rate and calculate the reaction kinetics of gas-solid reactions for the thermochemistry research and applied engineering technology development. As thermogravimetric analysis/differential scanning calorimetry (TG/DSC), the traditional thermal analysis instruments have been widely applied to the analysis of non-catalytic gas solid reactions, resulting in various non-isothermal kinetic calculation methods reaction models. In this study, the determination principle was highlighted and the main shortcomings of the traditional thermal analysis in gas solid reactions were also discussed. This was succeeded by a detailed analysis of the principle and characteristics of the isothermal differential Micro Fluidized Bed Reaction Analyzer (MFBRA) indigenously developed by IPE, CAS. Measuring some typical gas-solid reactions including decomposition, pyrolysis, combustion, reduction and adsorption demonstrated that the MFBRA was distinctively featured with its enabled fast heating, low inhibition of gas diffusion, in-situ reaction and isothermal differential characteristics. The further development trends in thermal analysis approach and instrument, including the further work on MFBRA were discussed.关键词
