P2-4B The exothermic reaction of stillbene (A) to form the economi- cally important trospophene (B) and methane (C), that is, was carried out adiabatically and the following data recorded: X A → B+ C 0 0.2 0.4 0.45 1.0 1.67 5.0 5.0 0.5 5.0 0.6 0.8 5.0 0.9 1.25 0.91 -TA (mol/dm³ min) The entering molar flow rate of A was 300 mol/min. 1. Calculate the batch reactor (BR) times to achieve 40% and 80% conversion when 400 moles of A are charged to a 400 dm³ reactor. 2. What are the PFR and CSTR volumes necessary to achieve 40% conversion? (VPFR = 72 dm³, VCSTR = 24 dm³) 3. Over what range of conversions would the CSTR and PFR reactor volumes be identical?
