| Abstract | Na-ZSM-5 zeolite with Si/Al molar ratios in the range of 10-50 was synthesized and then transformed into HZSM-5 using ion-exchange method. Techniques such as XRD, FT-IR, SEM, EDX, TG-DTA, BET and NH3-TPD were used to characterize the zeolite. Light olefins oligomerization reaction was studied over HZSM-5 zeolite catalyst with Si/Al molar ratios in the range of 10-50. The reaction was carriedout at atmospheric pressure, temperature in the range of 250 400°C and GHSV = 195-1170 h. The study showed that by increasing the temperature from 250 to 300°C, the C 7 hydrocarbons in the product increased, whereas above this temperature, they decreased. Similarly increase in GHSV caused the C7 hydrocarbons in the product to decrease. The highest C7 hydrocarbons were obtained with HZSM-5 of Si/Al molar ratio = 25, at temperature 300°C and GHSV = 195 h. |
