- Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2. (a) Calculate the percentage excess O2 fed to the furnace. (b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as: 2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain howarrow_forwardEnumerate the various methods for catalyst preparation and discuss vividly any one of the methodsarrow_forward2. Design a spherical tank, with a wall thickness of 2.5 cm that will ensure that no more than 45 kg of hydrogen will be lost per year. The tank, which will operate at 500 °C, can be made from nickel, aluminum, copper, or iron (BCC). The diffusion coefficient of hydrogen and the cost per pound for each available material is listed in Table 1.
