National Exams / EGBC — May 2015 — 04-Chem-A4 Chemical Reactor Engineering. Three-hour open-book exam; the designated Fogler textbook (any edition), unit-conversion / mathematical tables (CRC Handbook) and a non-communicating programmable calculator are permitted. Five questions are printed and any four constitute a complete paper (each worth 20 marks); all five are solved below for completeness. No credit is given for re-deriving standard rate expressions, so the batch / MFR / PFR design equations are quoted and applied. Property look-ups not printed on the paper (molar masses, the gas constant) are stated explicitly in each Given block as permitted open-book references.
Reference texts: H. S. Fogler, Elements of Chemical Reaction Engineering (4th/5th ed., Prentice Hall) — the designated open-book text: batch/CSTR/PFR design equations, the stoichiometric table with expansion factor $\varepsilon$ for gas-phase reactions with a change in moles, and reversible-reaction kinetics; O. Levenspiel, Chemical Reaction Engineering (3rd ed., Wiley) — non-ideal flow (dead-zone / bypass models), the dispersion and tanks-in-series RTD models, and rate-equation determination from a differential (mixed) catalytic reactor; supporting property data from Perry’s Chemical Engineers’ Handbook (9th ed.).
