Comparison of the effect of treated kaolin and metakaolin as the matrices in the SAPO-۳۴spray-dried catalyst for converting methanol to light olefins

With using kaolin and metakaolin treated as matrix in the formation of SAPO-۳۴ catalyst for thereaction of methanol to light olefins۱, the metakaolin-based SAPO-۳۴ catalyst outperformed the kaolin-basedcatalyst with ۸۲% selectivity in MTO conversion. The selectivity of propene and ethane in both catalysts wasaround ۷۲%. Both catalysts were stable for ۱۲۰۰-۱۵۰ minutes.
