Styrene can be made by catalytic dehydrogenation of ethyl benzene. The reaction is usually carried out in the presence of steam, which acts as a heat carrier and reduces coking on the catalyst. If a mixture of steam and ethyl benzene is fed to an adiabatic reactor at 2 bar, 640 °C, estimate the equilibrium conversion and outlet temperature as a function of the ratio of steam to ethyl benzene. What ratio would you recommend using in practice?
The table below gives the enthalpy of benzene(1)-heptane(2) solutions at 20 °C 1 bar as a function of the mol fraction of benzene. Calculate and plot the excess enthalpy at 20 °C, 1 bar.
The product may bemobile or immobile; since the reaction is irreversible, it does not matter. Thisreaction shows the solute's penetration across the film. Write mass balancesfor the solute and the immobile reagent.
