Abstract
Silicoaluminophosphate-18 can be considered as an effective catalyst for methanol conversion to olefins (MTO). A series of SAPO-18 were prepared to investigate the effects of aging pretreatment on crystallization time. The results exhibit that stirring aging, in addition to reducing the overall particle size of SAPO-18, decreases the crystallization time from 168 to 65 h. Also, the effects of addition order of the reagents and crystallization time on physiochemical properties of the SAPO-18 nanoparticles were studied. Finally detailed investigations were carried out on the catalytic performance of the samples in MTO process and the best catalyst was determined.
