    (a) oxygen/coal ratio = 0.8 (b) oxygen/coal ratio = 1.2 (c) oxygen/coal ratio = 1.6 (d) oxygen/coal ratio = 2.0. As the amount of oxygen increases, more CO will be consumed to produce CO 2 . The reaction between CO and water is a slightly exothermic reaction, so a higher temperature will result in a lower CO conversion and a higher concentration of CO in the product.
