Abstract :
The catalysts prepared by modifying SAPO-34 molecular sieve catalyst with Transition metals (Zn, Ni, Co, and Fe) by hydrothermal method were investigated for methanol conversion to light olefins (MTO). And the prepared catalysts were characterized by XRD and SEM. The catalytic properties of the modified molecular sieves were evaluated through a fixed bed reactor. The results showed that the ethylene yield of ZnSAPO-34 was increased by 3.2% and total yield of ethylene and propylene was increased by 5.0%.
