dc.description.abstract | Bimetallic (Pt or Pd and Ga) catalysts were prepared by consecutive impregnation on mordenite. The catalyst wasfurther impregnated with potassium (K) to reduce its acidity. The catalysts were characterized by X-ray diffraction(XRD), nitrogen adsorption (BET) and ammonia temperature programmed desorption (NH3-TPD). The catalyticactivity of the bimetallic catalysts was compared with the monometallic catalysts in conversion of n-hexane. A highercatalytic activity was obtained for Pt catalyst in comparison with Pd sample under the same reaction condition:catalyst 1 g, weight hourly space velocity (WHSV) of 1, 1 h time on stream and reaction temperature at 400°C. Theresults indicate that Ga incorporation changes the product selectivity, selectivity towards dehydrogenation products was increased but selectivity towards isomerization products was decreased. The catalyst with K addition, 0.5 Pt/1Ga/3% K/M exhibits enhanced selectivity to aromatics (9.5%) which is due to decreased acidity of the catalyst. | en_US |
