چكيده لاتين :
Dehydrogenation of Propane was carried out in a laboratory scaled reactor over an industrial Pt-Sn/Al2O3
catalyst. To obtain proper kinetic data for determination of intrinsic reaction rate, it was necessary to perform
experiments in the absence of external and internal mass transfer limitations. Experiments were conducted using
catalyst particles of different sizes to investigate internal mass transfer limitations. Feed flow rates were also varied over
a wide range, keeping WHSV constant to investigate external mass transfer limitations under reaction conditions. The
results were compared with theoretical predictions and good agreement was observed.
