Universidad de Zaragoza Comparison of Conventional and Two-Zone Fluidized Bed Reactors for Methanol to Olefins. Effect of Reaction Conditions and the Presence of Water in the Feed 2022 Access copy available to the general public Unrestricted The effect of water over the performance of the Methanol-to-Olefins process was studied in a conventional fluidized bed reactor (CFBR) and a two-zone fluidized bed reactor (TZFBR). Both of them contained the same SAPO-34-based catalyst, prepared by agglomeration with bentonite and alumina. In the first section of this paper, the performance was studied in the TZFBR for a wide range of temperatures (350-600 °C, ¿T = 50 °C), and two oxygen concentrations fed to the lower zone (7.5 and 10.8% for 500, 550, and 600 °C). In the second section, a comparison between the performance over the two previously mentioned reactors is presented, followed by a comparison between feeding water or not doing so to the TZFBR. Results showed that the TZFBR increased the initial yield to olefins and the production time of them, an effect that was increased by feeding a mixture of methanol-water (1:1 molar ratio) instead of pure methanol. info:eu-repo/grantAgreement/ES/MICINN/BES-2017-082052 info:eu-repo/grantAgreement/ES/MICINN/CTQ2016-76533-R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.2 2022 ENGINEERING, CHEMICAL 48 / 141 = 0.34 2022 Q2 T2 0.819 2022 Chemical Engineering (miscellaneous) 2022 Q1 Industrial and Manufacturing Engineering 2022 Q1 Chemistry (miscellaneous) 2022 Q1 7.6 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lasobras, J.
