Universidad de Zaragoza (orcid)0000-0002-4546-4111 Gas-solid contactors and catalytic reactors with direct microwave heating: current status and perspectives 2023 Access copy available to the general public Unrestricted Microwave heating (MWH) transforms energy from an electromagnetic wave to heat. In contrast to conventional heating (CH) mechanisms that use slower heat transfer processes via conduction, convection or radiation, microwaves (MW) directly interact with MW susceptor materials and induce a rapid conversion of the electromagnetic energy into heat. This rapid heating provides MWH with distinct features that can be leveraged to increase conversion, selectivity and/or energy efficiency of chemical processes. Here we discuss recent significant advances reported in MWH processes involving gas-solid interactions. Special attention is devoted to key aspects such as the methodologies to accurately determine local temperatures under the influence of electromagnetic (EM). Other relevant aspects such as the consideration of the solid catalyst dielectric properties or the design of novel gas-solid contactor configurations will be discussed. Emerging aspects such as the potential of MWH to minimize secondary by-products in high temperature reactions or to efficiently perform in transient processes, e.g. adsorption-desorption cycles, are highlighted. Finally, current challenges and perspectives towards a wide application of MWH in gas solid contactors will be critically discussed. info:eu-repo/grantAgreement/ES/DGA-FSE/CIBER-BBN info:eu-repo/grantAgreement/EC/ERC/267626/EU/Microwave-Microwave-Assisted Microreactors: Development of a highly efficient gas phase contactor with direct catalyst heating /HECTOR info:eu-repo/grantAgreement/EC/H2020/680777/EU/Adaptable Reactors for Resource- and Energy-Efficient Methane Valorisation/ADREM This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 680777-ADREM info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.2 2023 CHEMISTRY, APPLIED 13 / 74 = 0.176 2023 Q1 T1 ENGINEERING, CHEMICAL 35 / 170 = 0.206 2023 Q1 T1 CHEMISTRY, PHYSICAL 60 / 178 = 0.337 2023 Q2 T2 1.022 2023 Chemistry (miscellaneous) 2023 Q1 Catalysis 2023 Q2 11.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Mallada, Reyes Universidad de Zaragoza (orcid)0000-0002-4758-9380 Santamaría, Jesús Universidad de Zaragoza (orcid)0000-0002-8701-9745 5005 555 Universidad de Zaragoza Dpto.
