MODULE 6 11. Toluene reacts with H₂ to form benzene (B), but a side reaction occurs in which a by-product, diphenyl (D), is formed: C7H8 + H₂ -> C6H6 + CHA Toluene Hydrogen Benzene Methane C7H8 + H₂ C12H10 Diphenyl The process is shown below. Hydrogen is added to the gas recycle stream to make the ratio of H₂ to CH4 1 to 1 before the gas enters the mixer. The ratio of H₂ to toluene entering the reactor at G is 4 to 1. The conversion of toluene to benzene on one pass through the reactor is 80%, and the conversion of toluene to the by-product diphenyl is 8% on the same pass. Calculate the moles of Ra and moles of R₁ per hour.
