  Silicoaluminophosphate (SAPO) zeotype materials, a family of zeolites with micropores, have moderate acid strengths compared with conventional aluminosilicate zeolites; furthermore, their acid amounts can be tuned by the incorporation of Si species into the aluminophosphate (AlPO) framework. The conversion of methanol to light olefins including ethene, propene, and butenes (isobutene, 1-butene, and 2-butenes), methanol-to-olefins (MTO) reaction, is carried out over zeolites as an acid catalyst. In the MTO reaction, the enhancement of the diffusivity of reactants and products and the tuning of the acidity of zeolites are crucial keys to the improvement of the catalyst life due to the suppression of the coke deposition in the pores. In the present study, we have focused on the improvement of the catalytic performance of SAPO-5 materials with the AFI str.. View More»
