b) If the reactor above is packed with inert ceramic
spheres with a diameter of 5 mm and a bed voidage of 0.45,
determine the pressure drop across the reactor. Additionally, the
reactor length-to-diameter ratio is now set to 8:1 and you can use
an average process gas viscosity of 26.8·10-6 kg/m·s. Average gas
density can be calculated using the ideal gas law.
Consider the reaction below for the production of benzene via homogeneous thermal dealkylation of the toluene in the temperature range of 700 °C to 950 °C. -0.5 m3 CyHg + H2 → C6H6 + CH4 mol Prol = 3 · 1010 e 25,614/T[K]CT01C9;5 s] Where concentrations of reactants are in mol/L reactor and the temperature is in K. The heat of reaction is - 52.0 kJ/mol (at 900 °C) and -50.5 kJ/mol (at 700 °C), and the average specific heats of the reactor feed and effluent are 3.3216 kJ/kg:K (at 950 °C) and 3.042 kJ/kg-K (at 700 °C). a. If feed enters the reactor at 700 °C and 25 bar, solve the material and energy balances for a plug flow reactor to determine the volume of reactor needed to give 90% conversion of toluene. Do not use a process simulator for this portion The feed to the reactor comprises 80 kmol/hr of toluene and 320 kmol/hr of hydrogen. Plot the conversion and temperature profiles in the reactor versus reactor volume.
