The structure was analyzed by X-Ray diffraction (XRD) confirming the formation of the perovskite phase with some TiO2 anatase phase in all the catalysts. Microwave irradiation decreases the temperature and time of synthesis from 220 °C for 24 h (conventional heating) to 180 °C for 1h, without affecting the formation of perovskite. A 7 wt. % ruthenium-doped SrTiO3 catalyst showed the best dielectric properties, and thus its catalytic activity was evaluated for the methane dry reforming reaction under microwave heating in a custom fixed-bed quartz reactor. Microwave power, CH4:CO2 vol. % feed ratio and gas hourly space velocity (GHSV) were varied in order to determine the best conditions for performing dry reforming with high reactants conversions and H2/CO ratio. Stable maximum CH4 and CO2 conversions of ~99.5% and ~94%, respectively, at H2/CO ~0.9 were possible to reach with the 7 wt. % ruthenium-doped SrTiO3 catalyst exposed to maximum temperatures in the vicinity of 940 °C. A comparative theoretical scale-up study shows significant improvement in H2 production capability in the case of the perovskite catalyst compared to carbon-based catalysts.2018http://zaguan.unizar.es/record/7871210.1016/j.cep.2018.03.024http://zaguan.unizar.es/record/78712oai:zaguan.unizar.es:78712info:eu-repo/grantAgreement/EC/FP7/267348/EU/Towards Perfect Chemical Reactors:Engineering the Enhanced Control of Reaction Pathways at Molecular Level via Fundamental Concepts of Process Intensification/TOPCHEMCHEMICAL ENGINEERING AND PROCESSING 127 (2018), 178-190by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
