Problem 7 The gas-phase reaction, 2A2 + B2 2A2B, is carried out in a constant- volume reactor (volume V) at temperature T. No g-moles each of A2 and B2 are charged to the reactor, which is evacuated...
The second order gas phase irreversible reaction: 2.4-B is carried out in an isothermal batch reactor containing 40 kg of catalyst and with an initial volume of 60-liter. The reactor is initially filled with equal molar quantities of A and inert I at 300 K and 2.5 atm. Calculate the time needed for the concentration of product (B) to be 0.02 mole/liter if: a) the reaction takes in a constant pressure batch reactor (3 points) b) the reaction takes place...
Exercise 4.4: Catalyst deactivation in a batch reactor Consider the irreversible, liquid-phase isomerization reaction carried out in a solvent containing dissolved catalyst at 25°C in a batch reactor Aka B The apparent first-order reaction-rate constant, ka, decreases with time because of cat- alyst deterioration. A chemist colleague of yours has studied the catalyst deactivation process and has proposed that it can be modeled by ka= Tt kat in which k is the fresh catalyst rate constant and ka is the...
7. (15 pts.) A gas-phase reaction (A+B-C+D) is carried out in a packed bed reactor. When the particle size was decreased by 15 %, the conversion remained unchanged. When the particle size was decreased by 20%, the conversion decreased. When the original particle size was increased by 15 %, the conversion also decreased. In all cases, the temperature, the total catalyst weight, and all other conditions remained unchanged. Explain the observation. 7. (15 pts.) A gas-phase reaction (A+B-C+D) is carried...
The elementary gas phase reaction (A <--> 2B) is to be carried out in an adiabatic CSTR. The feed which is at a temperature of 27oC, consists of 80% of A and the remainder inerts. The volumetric flow rate entering the reactor at this temperature is 100 l/min. The concentration of A in the feed at 27oC is 0.5 mol/liter. For 80% of the adiabatic equilibrium conversion, calculate the required reactor volume. DATA: CpA=12 J/mol.K; CpB=10 J/mol.K; CpI=15 J/mol.K deltaHrxn=-75000...
