Q2: Second Order Reaction Carried Out Adiabatically in a CSTR. The acid-catalyzed irreversible liquid-phase reaction is: A The feed, which is equimolar in a solvent and A, enters the reactor at a total volumetric flow rate of 10 dm/min with the concentration of A being 4 M. The entering temperature is 300 K. (a) What CSTR reactor volume is necessary to achieve 70% conversion? (b) Redo part (a) if the feed temperature was raised to 340 K. (c)comment on the results of (a) and (b) in regards to the effect of feed temperature on the exit temperature and volume required. Given: AHR (300 K) = -3300 cal/mol - °C CP. = 15 cal/mol. °C C, = 15cal/mol. °C CPs = 18 cal/mol. °C k(300 K) = 0.0005 dm /mol-min E= 15,000 cal/mol

A first order, liquid phase endothermic reaction A -> B + C, is conducted in a CSTR of 25 m3 volume operating at steady state. The feed concentration of A is 1.2 mol/L and enters the reactor at 8.7 L/s at 300 K. However, the reactor is heated in order to increase the rate and to achieve a conversion of 80%. a) Determine the temperature and heat transfer (kJ/s) requirement of the reactor needed to achieve this conversion. b) It is suggested to add a heat exchanger and a second reactor in series with the first CSTR. The coolant fluid enters and exits the reactor at a constant temperature which is less by 100 K from the exit temperature of the first reactor. Both reactors operate at the similar temperature. Calculate the conversion exiting the second reactor. Given that UA=2.3 kJ/s*K for which U is the overall heat transfer coefficient and A is the heat transfer area.

Question 1) The gas phase reaction (A→ B+C) must be carried out in a fixed-bed tubular reactor using a solid catalyst in a spherical shape of 0.4 cm in diameter. The reactor must operate isothermally at 573 K and an inlet pressure of 1 atm. The reaction is first order and the reactor is fed with pure A at a molar flow of FA0-1 g-mol/s. The internal diameter of the reactor must be 2.54 cm.It is known: -The reaction on the surface of the catalyst is of the type r₁=kCA.; -The particle density gp=2 g/cm3; -The porosity of the bed gl= 0.40.-This reaction, when carried out using the catalyst in powder form, obtained a speed of R 1 10-3 g-mol/g-cat.s, at a temperature of 573 K and pure reagent A at a pressure of 1 atm .-Consider that the reactor is being operated under conditions free from resistance to external mass transfer to the particle.-The effective molecular diffusivity in the gas phase (DAB) to solve this exercise must also be considered constant with the temperature and composition…
