Question
Problem B 3. Toluene reacts with H, to form berzene (B), but a side reaction occurs in which a by- product, diphenyl (D), is formed: C,H, CH, Benzene CH, (a) Toluene Hydrogen Methane 20,H, + H; - CH» + 2CH, Diphenyl The process is shown in Eigure P6 3.19 Hydrogen is added to the gas recyele stream to make the ratio of H, to CH, 1 to 1 before the gas enters the mixer. The ratio of H, to toluene entering the reactor at G is 4H, to I toluene. The conversion of toluene to benzene on one pass through the reactor is 80%, and the comersion of toluene to the by-product (b) diphenyl is 8% on the same pass. Makeup M 100% H Gas recycle Ra P Purge only CH. Feed 100% toluene 3450 Ibhr Gross Teed B Benzene 100% Mixer Reactor Separator Liquid recycle R 100% toluene Diphenyl 100% Figure P6.3.19 Calculate the moles of Ra and moles of R per hour. Data: Compoundi CH, CH, CH, CH MW: 16 78 92 154
