Abatch reactor operating at near room temperature, 25°c, is currently takin ninety percent conversion for an irreversible second-order liquid-phase reaction. the time to fill, empty, and clean the reactor, this allows one batch to be handled during an eight hour work shift. g six hours to reach accounting for there is now pressure to cut the reaction time in half, to three hours, so two batches can be handled during a shift. when the reactor temperature is increased to 35 c, the time to reach ninety percent conversion is reduced to five hours. ermine the product of the reaction rate constant and initial reactant concentration (kcao) that corresponds to achieving ninety percent conversion in six hours, five hours, and three hours. note that three answers, one for each reaction time, are required determine the activation energy for this reaction (or e/r where e is the activation energy and r is the ideal gas constant). note that the initial reactant concentration (cao) can be taken to be constant, independent of temperature specify the reactor temperature that should be used to achieve ninety percent conversion in the desired three hours. this temperature must be known to examine safety issues and to determine the heat transfer requirements associated with the new reactor temperature (although these aspects are not part of the current problem).

We want to simulate a gas phase reaction in a packed bed reactor using a silica alumina catalyst. the reaction can be assumed to be like the following- 2a b +c (reversible reaction) reaction rate constant, k, = 4.25x10-6 mol atmgm cats and k = 2.5 the molar flow rate into the packed bed reactor is 23.6 mol/s and the entering pressure is 18 atm. assume there is no pressure drop or temperature change in the reactor. [a] write the mole balance? [b) write the rate law in terms of partial pressure? [c] setup a stoichiometric table for this reaction. [d] write the partial pressure in terms of conversion. [e] write the rate law in terms of conversion only. [f] what is the equilibrium conversion xc? [g] how many kilogram of catalyst you will need to have a conversion 90% of xe in a packed bed reactor? [h) how many kilogram of catalyst you will need to have a conversion 90% of xe in a fluidized bed reactor? what conversion would be achieved if you use a packed bed reactor with 100 kg catalyst with a pressure drop parameter a =0.0098 kg! at what catalyst wt the pressure drop falls below 1 atm?

The gas-phase dehydrogenation of ethane to ethylene and hydrogen: сно сна + н, is carried out in a flow reactor with no pressure drop. the reaction is irreversible and it reaction rate is first order with respect to ethane concentration and, i.e. takca where rate of reaction of ethane (a), in moll-1s-1 specific rate constant, in s1 concentration of ethane (a), in moll-1 k = ca = the reactor is fed continuously with a mixture of gaseous components ethane and steam (an inert gas). the mixture is composed of 40 mol% ethane and 60 mol% steam. the gas mixture enters the reactor at 2 bar pressure with a total molar flow rate, fo, of 150.0 mols at a temperature of 700 °c. at this temperature the rate constant, k, for the reaction is 0.131 s1. calculate: i) the entering concentration of ethane, cao (in moll-1) ii) the entering volumetric flow rate of gas, vo (in ls1) iii) the expansion factor, e iv) the conversion of ethane if the reactor is a cstr of 50 m3 volume. v) the mole fraction of ethane, ethene, hydrogen and steam in the outlet stream from the reactor. a) if the outlet stream from the cstr (from part (iv)) is fed into another cstr, what volume (in l) of this reactor would be necessary for an overall conversion of 80% for ethane? b) if the outlet stream from the cstr (from part (iv)) is fed into a pfr, what volume (in l) of this reactor would be necessary for an overall conversion of 80% for ethane? assume the gases are ideal and the reactor is maintained at the same temperature and pressure as the inlet conditions. data: ideal gas constant, r = 8.314 kpalmol-1k-1 = 8.314 jmol-1k-1
