Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase reaction: C7H16àC6H5CH3+4H2
Pure heptane at 400 oC is fed to the reactor. The reactor operates isothermally at 400 oC and the reaction goes to completion. Data: The average heat capacity of n-heptane between 25 oC and 380 oC is 0.2427 kJ/(mol.oC). Take a basis of 1 mol of heptane fed. Using elemental species C(s) and H2(g) at 25 oC as reference state. Calculate the required heat transfer to or from the reactor in kJ

Sulfur dioxide (SO2) and hydrogen sulfide are toxic byproducts of many industrial processes. To prevent their release to the environment, they can be neutralized to form elemental sulfur through the Claus process, which follows the reaction: 2H2S + SO2 + 2H20 + 35 You have been tasked with neutralizing sulfur dioxide and hydrogen sulfide in a continuous reactor. The reagents arrive in stoichiometric proportion at 250°C and 100 kPa. The feed flowrate is 10...
