2. An aqueous glucose stream is to be catalytically hydrogenated to sorbitol in a slurry tank reactor. Feeds to the reactor are an aqueous glucose stream with a concentration of 2.6kgmol / m^3 at a flow rate of 10^-3m^3/ s and a 120 percent of stoichiometric hydrogen gas stream. The reactor is to be operated isothermally at 423K, where the reaction is observed to follow the kinetics shown here:
-r_glucose =k c_hydrogea ^0.6 c_glucose k_423K=3.76\times 10^-4(kgmol / m^3)^-0.6s^-1
The reaction is conducted at 10,000 kPa, the solubility of hydrogen may be assumed to be 5kgmol / m^3 at this pressure. The actual kinetics of the reaction require adjustment to account for catalyst masstransfer effects. Neglecting these effects, calculate the conversion for a 2-m^3CSTR.
