Abstract: The investigation focused on modifying SAPO-34 zeolite with alkaline earth metals to increase the anti-coking ability of the catalyst in methanol conversion to light olefins (MTO). 1%Ba/SAPO-34 gave a prolonged lifetime by 27% compared with SAPO-34 under the reaction conditions of WHSV = 2 h?1, 450 oC, and atmospheric pressure.

Key words: alkaline earth metal, modification, SAPO 34, methanol-to-olefin, coke deposition, lifetime
