Part I Describe on the concept of integral reactor, and differential reactor (*refer to Chapter 5 of Fogler for preliminary reading)

Part II For a methane cracking reaction that happens in a packedbed (weighing 0.250 gcatalyst) reactor at 800o C, the following reaction conditions are provided:

Inlet stream:

N2 flowrate (carrier gas) = 40 mL/min STP

CH4 flowrate (reactant) = 10 mL/min STP

Total flowrate (N2 + CH4) = 50 mL/min

Exit stream (steadystate conditions): Total flowrate (measured by flowmeter) = 55 mL/min STP CH4 composition from GC measurement = 0.10 (after 30 min of reaction) H2 composition from GC measurement = 0.10 (after 30 min of reaction)

Assume ideal gas

Catalyst property:

10wt%Ni supported on 90% Alumina

Bed porosity = Assume 50% void

From the data given, calculate and proceed to determine whether the obtained reaction rate is free from external and internal mass transfer limitation. Adopt the Differential Reactor analysis in your calculation.
