Abstract

In this investigation, HZSM-5 zeolite with AlCl3 as aluminum source were synthesized by hydrothermal method and modified with COBALT. HZSM-5 and Co/HZSM-5 zeolites were used to investigate the product distribution in LPG FUEL cracking. The prepared catalysts were characterized by XRD, FTIR, SEM, BET, XRF, NH3-TPD and Al MAS NMR analyses. The results of NH3-TPD showed that the acidity of Co/HZSM-5 zeolite was lower than HZSM-5. Aluminum distribution in the framework of HZSM-5 was determined by chemical analysis of XRF and reflectance UV-Visible analysis. The results indicated that the proportion of close Al atoms and single Al atoms in the zeolite framework was 28.6% and 71.4%, respectively. The obtained OLEFIN yield for Co/HZSM-5 (48.1%) was higher than HZSM-5 (45.4%) in catalytic cracking of LPG FUEL. The yield of C5+ heavy products, formed coke and deactivation rate for Co/HZSM-5 catalyst were lower than unmodified HZSM-5.
