摘要

An NaY-type zeolite membrane was employed for the catalytic dehydrogenation of cyclohexane in a membrane reactor packed with Pt/Al2O3 catalysts. The reaction was carried out in the temperature range of 423?523 K over 1.0 wt.% Pt/Al2O3 catalysts. The conversion of cyclohexane in the membrane reactor increased beyond the thermodynamic equilibrium value due to the simultaneous removal of hydrogen and benzene from the feed side of the membrane. When the sweep flow rate was maintained at 100 cm3 (STP) min-1 and the cyclohexane feed rate was maintained at 1.1 mol h-1, the conversion of cyclohexane in the NaY-type zeolite membrane reactor reached 72.1 % at 473 K, compared to the calculated equilibrium value, 32.2 %. In addition, a mathematical model was developed to describe a combined process of the reaction in the catalyst bed and separation through the membrane. A good agreement between the calculated and the experimental values was obtained.
