Question: 1 . The A - > B + C exothermic reaction is carried out in a moving bed reactor. k = 0 . 3 3

1. The A->B+C exothermic reaction is carried out in a moving bed reactor.
k=0.33exp(E/R(1/450-1/T)) and E/R=3777 K. Heat is removed with water in the heat exchanger. A and inert enter the reactor at an equimolar speed of 40 atm and 20 dm3/s. Both the catalyst and the feed enter 450 K, and the heat transfer coefficient between the catalyst and the gas is infinite. The heat capacity of the solid catalyst is 100 J/kg.kat.K. Catalyst degradation is first order according to activity.
a) The refrigerant fluid in the heat exchanger moves in parallel flow at a speed of 10 kg/s and is fed at 50 oC. What is the catalyst loading rate (kg/s) that will give the highest conversion? What is the transformation at this speed?
b) The refrigerant in the heat exchanger moves in parallel flow at a speed of 10 kg/s and is fed at 50 oC. What is the catalyst loading rate (kg/s) that will give the highest conversion? What is the transformation at this speed?
kd=0.01(700 K(1/450-1/T))s-1. Determine the amount of catalyst to be used in the bed in kg.
CpA=40 J/mol. K, CpB=25 J/mol. K, CpC=15 j/mol.K H(T)=-80 kj/mol A
