Enhancement of catalytic performance of ZSM-5 zeolite through desilication and re-assembly in MTP process

Hierarchical ZSM-5 zeolites were synthesized by alkaline desilication and a surfactant induced re-assembly. The prepared catalysts were characterized by XRD and FE-SEM techniques. The catalytic performances of synthesized catalysts were studied for methanol to propylene (MTP) reaction in a fixed-bed reactor at T = 480 °C, P = 1 atm, methanol WHSV = 0.9 h-1 with methanol to water weight ratio of unity. The results showed that desilication with surfactant, increased propylene and light olefins selectivity.
