Characteristics of coal partial gasification experiments ...
As oxygen-coal ratio increases, the carbon conversion keeps increasing from 79% to 88%. It indicates that if 79% is achieved, 0.38 oxygen-coal ratio is required, while 88% is achieved, 0.80 oxygen-coal ratio is needed. Therefore, in the low-reaction rate stage of gasification, 0.42 oxygen-coal ratio only realizes 10% carbon conversion.
