The preferential heating of the solid monolith (made of SiC, a good microwave susceptor), allows working with a lower gas phase temperature, reducing the formation of undesired by-products in the gas phase via homogeneous reactions. Conversion levels of ~ 21% and selectivity to propylene up to 70% have been achieved with MW-heated straight channel monolithic reactors coated with a VMgO catalyst. These competitive values contrast with the more limited performance delivered by the same catalytic system when it is subjected to conventional heating in a fixed-bed reactor configuration, thereby corroborating the advantage of working under a significant gas–solid temperature gap to minimize the extent of homogeneous reactions. 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/ 13.273 2020 ENGINEERING, ENVIRONMENTAL 2 / 53 = 0.038 2020 Q1 T1 ENGINEERING, CHEMICAL 4 / 143 = 0.028 2020 Q1 T1 2.528 2020 Chemical Engineering (miscellaneous) 2020 Q1 Industrial and Manufacturing Engineering 2020 Q1 Environmental Chemistry 2020 Q1 Chemistry (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Hueso, José Luis (orcid)0000-0002-4546-4111 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.
