In underground coal combustion in the gas phase several reactions take place, including CO + ½ O2 ? CO2 H2 + ½ O2 ? H2O CH4 + 3/2 O2 ? CO + 2 H2O where the CO, H2, and CH4 come from coal pyrolysis. If a gas phase composed of CO 13.54 %, CO2 15.22 %, H2 15.01 %, CH4 3.20 %, and the balance N2 is burned with 40 % excess air, (a) how much air is needed per 100 moles of gas, and (b) what will be the analysis of the product gas on a wet basis?
