Abstract: The effect of temperature and Fe loading over HZSM-5 catalyst in thermal-catalytic cracking of naphtha for the production of light olefins has been studied. The temperature and loading were varied in the range 620-680 C and 2-10 wt% Fe, respectively. The results show that ethylene increases with temperature, while the propylene shows an optimum at 650 C. Addition of Fe to HZSM-5 had a beneficial effect on the production of light olefins up to 6% of loading. The yield of ethylene at 680 C and 6% Fe compared to unmodified zeolite increased by 14.9%. Excess amount of loading has reduced the conversion of naphtha which leads to drop in light olefin yields.
