In the hydrodealkylation of toluene to benzene, the following reactions occur:
C₇H₈ + H₂ → C₆H₆ + CH₄
2C₆H₆ ⇋ C₁₂H₁₀ + H₂
Toluene 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_____.
