摘要

Since all thermal reactions almost conduct under the unsteady conditions and those parameters including concentration and flow rate of evolved gas also change with the temperature or pressure, it is hard to clearly describe the reaction feature by only one parameter such as concentration in the Arrhenius equation. In fact, the concentration only indicates the relationship between the individual value and the total value of evolved gas. Thus, even if the concentration of some components in one complicated reaction increases, the real reaction would not increase since the other components maybe increase more intensively. On the contrary, the flow rate can give persuasive information to understand the characteristic of these reactions. A novel method of Equivalent Characteristic Spectrum Analysis (ECSA) has given the flow rate of all components, including mass flow rate or molar flow rate, by mass spectrum of TG-MS. This technology has been applied to analyze the feature of reaction process. As some applications in the materials field, ECSA has exactly detected the flow rate of hydrogen in the materials of storage hydrogen to evaluate its performance and construction. In the fossil energy, ECSA has found some principles how to control the pollutants and metal elements releasing problems during coal conversion. At present, ECSA has developed deeply to explain precisely the organic thermal reaction of biomass, oil, polymer, paraffin and so on since it has been applied to new instrument with double modes of EI and PI ionization and Skimmer interface for actual in-suit detect.
