Ra. Saymeh et al., AROMATIZATION OF N-HEPTANE OVER PT AND PT-CE SUPPORTED ON JORDANIAN CLAYS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(6), 1995, pp. 546-549
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.
