| Abstract Scope |
The gasification reactivity of the modified coal is lower than that of the raw coal, and it shows the same law in the CO2 atmosphere and the water vapor atmosphere, which is due to the extremely low ash content in the modified coal and the weakening of the catalytic effect of minerals. The reactivity of KL, GD and ZS raw coal and modified coal is better than that of CO2 atmosphere in water vapor atmosphere, the starting reaction temperature is lower and the maximum reaction rate is higher in water vapor atmosphere, and the reaction curve moves to the low temperature section, and the reaction curve of XB raw coal has the same response in water vapor and CO2 atmosphere, and the reaction curve basically coincides. |
