Abstract
Aromatization of n-heptane over Pt and Pt-Ge supported on Jordanian na tural clays has been investigated. The conversion of n-heptane at 510 degrees C over Pt-Ce/montmorillonite and Pt-Ce/kaolinite has been foun d to be 80% and 75% respectively after 3 hr. The activity of the catal yst used is in the sequence; Pt-Ce/montmorillonite > Pt/montmorillonit e > Pt-Ce/kaolinite > Pt/kaolinite. All catalysts show high percentage formation of toluene at the temperature range of 510-550 degrees C, w ith Pt-Ce/kaolinite having the highest percentage, The percentage of m ethane increases above this temperature range and reaches 100% at 600 degrees C. The increase of the hydrogen flow rates from 20 ml/min to 1 00 ml/min decreases the percentage of formation of toluene.
