17.16 Catalytic converters on automobiles are designed to minimize the NO and CO emissions derived from the engine exhaust. They generally operate between 400C and 600C at 1 bar of pressure. K.C. Taylor (1993. Cat. Rev. Sci. Eng. 35:457.) gives the following compo- sitions in ppm, molar basis) for typical exhaust from the engine: NO CO 02 CO2 N2 H2 HO hydrocarbons(-propane) 1050 6800 5100 135000 724000 2300 125000 750 The additional products of the effluent stream include NO2, N,O, N204, and NHz. Estimate the compositions of all species at each temperature (400C, 500C, 600C) and plot the ratio of NH, CO as a function of temperature. (Note: Use the options of the Solver soft- ware to set the precision of the results as high as possible.) 17.16 Catalytic converters on automobiles are designed to minimize the NO and CO emissions derived from the engine exhaust.
