Title
FeHZSM-5 molecular sieves – Highly active catalysts for catalytic cracking of isobutane to produce ethylene and propylene
Abstract

Fe-modified HZSM-5 catalysts were firstly used for catalytic cracking of isobutane, and the influence of Fe-loading on the catalytic performances of FeHZSM-5 catalysts for the cracking of isobutane was also investigated. The results indicated that both the isobutane cracking activity and the selectivity to light olefins of FeHZSM-5 samples with a small amount of Fe were greatly enhanced compared with the unpromoted HZSM-5, and very high yields of total olefins and propylene were obtained. For example, for the FeHZSM-5 sample loading with 0.010 mmol/g Fe the total yield of olefins reached 65.6%, and the yield of propylene was 32.4% at 625 °C.
