Aniline is produced by the hydrogenation of nitrobenzene. A small amount of cyclohexylamine is produced as a by-product. Nitrobenzene is fed to the reactor as a vapor with three times the required stoichiometric amount of hydrogen. The conversion of nitrobenzene to the products is 96% and the selectivity to aniline is 85%. Unreacted hydrogen is separated from the reaction products and recycled to the reactor. From the recycle line it is purged to keep the inerts in the recycle stream below 5%. The fresh hydrogen that is fed is 99.5% pure and the rest is inert. Determine the molar composition of the main product (in %). a) Nitrobenzene (%) b) Hydrogen (%) c) Aniline (%) d) Water (%) e) Cyclohexylamine (%)
