Chemical Reaction Engineering
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

In Langmuir treatment of adsorption,

Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule
Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site
