Ethylene epoxidation in microwave heated structured reactors 2016 Access copy available to the general public Unrestricted In the present work we show the microwave-induced heating of monolithic reactors containing a thin-layered catalyst that exhibits a strong and selective heating susceptibility under microwave irradiation. The combination of microwave radiation and structured reactors has been successfully applied for the intensification of the selective oxidation of ethylene to ethylene oxide (epoxidation) while operating at lower power consumptions and with higher energy efficiencies than in conventional heating conditions. The microwave radiation selectively heats the catalyst and the monolith walls while maintaining a relatively colder gas stream thereby creating a gas/solid temperature gradient of up to ~70 °C at a reaction temperature of 225 °C. Moreover, the influence of different parameters such as the distribution of the catalyst onto the structured monoliths or the temperature measurement techniques employed to determine the heating profiles (Optic Fibers and/or IR thermography) have been also thoroughly evaluated to justify the obtained catalytic results. info:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.636 2016 CHEMISTRY, APPLIED 6 / 72 = 0.083 2016 Q1 T1 ENGINEERING, CHEMICAL 12 / 135 = 0.089 2016 Q1 T1 CHEMISTRY, PHYSICAL 30 / 145 = 0.207 2016 Q1 T1 1.322 2016 Chemistry (miscellaneous) 2016 Q1 Catalysis 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4546-4111 Hueso, J.
