EXPERIMENTAL STUDY AND KINETIC ANALYSIS ON NO-CHAR REACTION
IntroductionDespite large amounts of literature about the reduction of nitrogen monoxide by char, the mechanism of the reaction is still not clearly understood, and there are large variations in the data of reaction. These variations can be attributed to the existence of many factors, such as parent coal rank, the catalytic inherent mineral matter, mass transfer limitations at higher temperatures and the effects of other gases etc. In this study, the coal char preparation was carried out in an entrained flow reactor (EFR) which can simulate the temperature and gas-phase environment in the near burner zone (flame region) of an industrial pulverized coal-fired furnace. The isothermal kinetic experiment was performed in a thermogravimetric analyzer (TGA). The purpose of this study was to explore the kinetics of the NO-char reaction in a wide temperature range 973-1573K.
