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. 000061591 536__ $$9info:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626 000061591 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000061591 590__ $$a4.636$$b2016 000061591 591__ $$aCHEMISTRY, APPLIED$$b6 / 72 = 0.083$$c2016$$dQ1$$eT1 000061591 591__ $$aENGINEERING, CHEMICAL$$b12 / 135 = 0.089$$c2016$$dQ1$$eT1 000061591 591__ $$aCHEMISTRY, PHYSICAL$$b30 / 145 = 0.207$$c2016$$dQ1$$eT1 000061591 592__ $$a1.322$$b2016 000061591 593__ $$aChemistry (miscellaneous)$$c2016$$dQ1 000061591 593__ $$aCatalysis$$c2016$$dQ2 000061591 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000061591 700__ $$0(orcid)0000-0002-4546-4111$$aHueso, J.
