Kinetic advantages of microwave activation in the dry reforming of methane:insights gained by SSITKA†
Utilising unexploited methane through its reaction with CO2 via the dry reforming of methane(DRM)has attracted attention.However,there are challenges related to catalyst deactivation and energy consumption due to the highly endothermic nature of the DRM;thus,microwave activation has been proposed to increase energy efficiency by directly heating the catalyst while minimising the heating of the reactor.In this study,we clarify the advantages of microwave heating in terms of more reactive coke formation during the reaction and enhanced reactivity under microwave conditions compared with conventional resistive heating.For the latter,steady-state isotopic transient kinetic analysis(SSITKA)was conducted to gain mechanistic insights,which suggested that microwave heating accelerated CO generation steps.This study shows that microwave activation can be advantageous in terms of reaction kinetics for the DRM.
