Abstract
In this contribution, the effects of ceria loading, Si/Al ratio, and reaction temperature on the catalytic performance of HZSM-5 catalysts for production of ethylene and propylene from light naphtha were investigated. The elaborated catalysts were characterized by XRD, FTIR, SEM, and BET specific surface area. The acquired results demonstrated that HZSM-5 structure was preserved after ceria addition. XRD patterns exhibited a crystallinity degradation of HZSM-5 samples by aluminum addition. Box-Behnken experimental design was utilized with central composite design for investigation of parameters such as reaction temperature (600–700 °C), cerium loading (2–14 wt%), and Si/Al ratio (25–125) in ethylene and propylene production. Analysis of variance (ANOVA) indicated the significance of the studied parameters and the corresponding interactions. The results exhibited that the highest ethylene yield was at the highest reaction temperature, the highest cerium loading, and the lowest Si/Al ratio. The superior propylene yield was attained at the highest Si/Al ratio whereas an optimum can be found for reaction temperature and cerium loading.
