The solids are a novel catalyst and a water sorbent that could be used to perform sorption-enhanced methanol synthesis; the operating conditions were selected accordingly to this process. The aim of this investigation was to find an expression for predicting the minimum fluidization conditions of a methanol synthesis catalyst and an adsorbent in the presence of their process stream and operating conditions. The findings of this study highlighted how umf (STP) decreases with a rise in temperature and increases with a rise in pressure, according to other works in the literature with different solids. Furthermore, the type of gas was found to influence the minimum fluidization velocity significantly. The experimental results agreed well with a theoretical expression of the minimum fluidization velocity adjusted for temperature, pressure, and viscosity. The choice of the expression for viscosity calculation in the case of gas mixtures was found to be of key importance. These results will be useful for researchers aiming to calculate the minimum fluidization velocity of a catalyst or other solids under reaction conditions using results obtained at ambient conditions with air or inert gas. info:eu-repo/grantAgreement/ES/MICINN/PDC2022-133066-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.0 2024 CHEMISTRY, PHYSICAL 83 / 185 = 0.449 2024 Q2 T2 0.746 2024 Physical and Theoretical Chemistry 2024 Q2 Catalysis 2024 Q3 7.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lasobras, Javier Universidad de Zaragoza (orcid)0000-0002-7488-6196 Soler, Jaime Universidad de Zaragoza (orcid)0000-0001-9022-2835 Herguido, Javier Universidad de Zaragoza (orcid)0000-0003-1940-9597 Menéndez, Miguel Universidad de Zaragoza (orcid)0000-0002-2494-102X 5005 555 Universidad de Zaragoza Dpto.
