In the hydrodealkylation of toluene to benzene, the following reactions occur:C₇H₈ + H₂ → C₆H₆ + CH₄2C₆H₆ ⇋ C₁₂H₁₀ + H₂Toluene and hydrogen are fed to a reactor in a molar ratio 1:5.80% of the toluene gets converted and the selectivity of benzene(defined as moles of benzene formed/moles of toluene converted) is 90%. The fractional conversion of hydrogen is

Chemical Reaction Engineering
For a heterogeneous catalytic reaction

A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important

The catalyst does not form an intermediate complex with the reactant

The surface of the catalyst does not play an important role during reaction

Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
