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 0.152 0.136 0.144 0.16 0.152 0.136 0.144 0.16 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by keff = k + kg keff = (k+ kg)/2 keff = (kkg)1/2 1/keff = 1/k + 1/kg keff = k + kg keff = (k+ kg)/2 keff = (kkg)1/2 1/keff = 1/k + 1/kg ANSWER DOWNLOAD EXAMIANS APP
