Choose the correct answers from the options given below.
We need to design a reactor in which the following steam reforming of methane is being done to produce hydrogen as per the following reaction:
CH4+H2O+206kJmolof heat longrightarrowCO+3H2
The reaction is endothermic and is to be carried out at high temperatures (800C) based on the desired output composition. All the species are in gas phase
but the reaction is catalytic. Reactants will have to diffuse to the catalyst which is coated on the bottom wall of the reactor(see Figure 1) between planes B and
C which are at a distance of 0.5L and 0.75L,respectively. The reactants are heated to the desired temperature by heating the gas mixture over the length of
the traverse between planes A and B. Further heating needs to be between planes B and C to provide thermal energy for the endothermic reaction.
For a given reactor of length L, height H and width W, flow rate and composition at the inlet and thermal wall boundary conditions on the bottom wall, we need
to find out how much conversion takes place, i.e., how much of the CH4 coming through the inlet gets converted to H2. We want to find this out using CFD
simulation. To begin with, assuming
Assuming steady, laminar flow, answer the following questions:
In order to model the effect of reactant concentrations on the chemical reaction rate correctly, which of the following needs to be specified
(i) The reaction rate constant (ii) reaction rate (iii) equilibrium constant
a.(i) only
b.(i) & (ii)
c.(i) & (iii)
d.(i),(ii) & (iii)
