Here, a series of hierarchical SAPO\u201034 catalysts were synthesized using a straightforward recrystallization method. The incorporation of triethylamine into the recrystallization mother liquor facilitated the formation of mesopores, achieving a high solid yield of up to 90%. Notably, the addition of phosphoric acid and ammonium polyvinyl phosphate alcohol during the recrystallization process significantly enhanced the crystallinity and regularity of the hierarchical SAPO\u201034 crystals, consequently increasing the mesopore size. Due to the substantially improved mass transfer efficiency and moderated acidity, the SP34\u20100.14P\u20100.06R catalysts exhibited a prolonged lifetime of 344\u2005min and 80.3% selectivity for ethylene and propylene at a weight hourly space velocity (WHSV) of 2\u2005h<jats:sup>\u22121<\/jats:sup>. This performance markedly surpasses that of the parent SP34 catalyst, which demonstrated a lifetime of 136\u2005min and a selectivity of 78.0%. Remarkably, the SP34\u20100.14P\u20100.06R maintained a lifetime of 166\u2005min even at a high WHSV of 10\u2005h<jats:sup>\u22121<\/jats:sup>, which is more than 5\u2010fold greater than that of the original microporous SP34. This research offers valuable insights into the design and development of hierarchically porous zeolites with high yields, enhancing the efficiency of MTO reactions and other applications.<\/jats:p>","DOI":"10.1002\/asia.202400436","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T13:19:36Z","timestamp":1715865576000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["High\u2010Yield Synthesis of Hierarchical SAPO\u201034 by Recrystallization Method for Efficient Methanol\u2010to\u2010Olefin Reactions"],"prefix":"10.1002","volume":"19","author":[{"given":"You","family":"Wu","sequence":"first","affiliation":[{"name":"Innovation Center for Chemical Science College of Chemistry Chemical Engineering and Materials Science Jiangsu Key Laboratory of Advanced Negative Carbon Technologies Soochow University  Suzhou 215123 P.
